Spiritual Multiplication

Have you ever stopped to think about how it is that you came to be a part of God’s family? What about the people who sit next to you at church each week? What about those in the church down the street? What about the estimated 2.6 billion Christians seeking to know and follow Jesus worldwide?

Well, as amazing as it is to consider, it is very likely that nearly every one of us can trace our faith story all the way back to a group of 12 unschooled, ordinary men who were Jesus’ first disciples. They were committed to sharing the good news of Jesus and seeing that message spread from believer to believer, generation after generation, right up to today! That’s the power of spiritual multiplication!

2,000 years later, Cru remains committed to this model for expanding God’s kingdom throughout the world and helping as many people as possible come to know and follow Jesus. So, what is spiritual multiplication, and why are we so committed to it as a movement?

Spiritual multiplication is a model for mission in which everyone is involved. Each new follower of Jesus shares the message they have received with people, who in turn pass it on to others. In this way, God’s kingdom can advance quickly, and the message of salvation through faith in Christ can spread far and wide. This model is one of the key distinctions between a ministry and a movement.

So, why do we believe so strongly in this model, and why are we committed to seeing spiritual multiplication take place in our movements?

Modeled in the Bible

First, we are committed to seeing spiritual multiplication take place in our movements because spiritual multiplication is modeled in the Bible. We have already discussed how the gospel has spread over the past two millennia though the faithfulness of a few key disciples and generations of believers who followed them. During His earthly ministry, we know Jesus multiplied His mission in the lives of His disciples through empowering them to baptize (John 4:2) and sending them out to proclaim the message of the kingdom (Luke 10:1-16). Others who were transformed by Jesus were given similar opportunities (Luke 8:39). In the parable of the sower, Jesus describes the fertile soil (a receptive heart) as someone who produces “thirty, sixty, and even a hundred times as much as had been planted!” (Matt. 13:8, 23)

We see this pattern continue in the life of the early church members. Paul exhorted Timothy to teach what he had been taught about Jesus “to other trustworthy people who will be able to pass them on to others.” (2 Timothy 2:2) In this one short verse, we see four generations of faith in Christ: Paul, Timothy, trustworthy people, and others!

As leaders, we must cast vision and create space for students to share their faith and disciple others.

Accelerates the Spread of the Gospel

Second, we are committed to spiritual multiplication because it allows the gospel to spread at an accelerated rate. You may remember seeing a similar model in your high school algebra class when you studied exponential growth functions. The financial industry also uses this thinking to grow wealth in the form of compound interest. Spiritual multiplication works in the same way!

Allow me to share a hypothetical example. Imagine a campus where four Cru leaders were each able to lead 10 people to Christ each year, but these new believers did not share their faith with anyone else. This is a model we call “spiritual addition.” After six years, 240 new believers would be added to the family of God! That sounds great, right?

But now consider what would happen if each of those same leaders were able to lead just two new people to Jesus each year. However, in this spiritual multiplication model, each of those new followers of Jesus did the same, year after year. In that scenario, after six years, 2,916 people would come to know Jesus! That is the power of spiritual multiplication!

Grounds Disciples in Their Faith

Third, spiritual multiplication grounds disciples in their own faith. People love to talk about the things they love. Whether it is the local sports team, a new restaurant, or a musician or artist, we naturally want to share the things we love with others. And often, in sharing the things we love, we find our love for them growing even stronger. Author and theologian C.S. Lewis once said, “We delight to praise what we enjoy because the praise not merely expresses but completes the enjoyment.”

The same is true of our relationship with Jesus. If Jesus has truly rescued us from sin and adopted us into His family, then it should only be natural that we would want to share that news with others and invite them into a relationship with Jesus as well. In doing so, we express the joy we have found in Christ, and that joy is enlarged in our own lives!

As new Christians share their faith with others, their faith will grow and they will increasingly delight in the God who loves them. Furthermore, when new believers actively share their faith, they typically see themselves as an important part of the movement, rather than just passive participants. They tend to stay more involved, help cast vision, and lead by example, so younger believers also become multiplying disciples.

C.S. Lewis once said, “We delight to praise what we enjoy because the praise not merely expresses but completes the enjoyment.”

Outlasts Any Individual

Last, we strive towards spiritual multiplication because it goes well beyond the scope of any individual. Spiritual multiplication grows faster and can outlast any individual leader within a movement. In fact, when spiritual multiplication is really taking place, much of the fruit of the movement may not even be known by those who would be seen as “leading” the movement, as the gospel runs down various relational tracks and expands into ever-increasing circles of influence.

In campus ministry, we sometimes ask ourselves, “Are we here to reach people, or see people reached?” If we are simply here to reach people, then the ministry is really about us, our influence, and our sense of significance. We will never impact the world beyond our very limited time, resources, and availability. But, if we are there to see people reached, we will invite others into the mission with us, trust God with the results, and expect to see a much larger impact in the world.

Three Challenges to Spiritual Multiplication

In order to embrace and implement a movement of spiritual multiplication, it is important that we identify and overcome some challenges and false beliefs that can serve as potential obstacles to our success.

1) I Don’t Know How to Create a Movement of Spiritual Multiplication.

For many of us, we have never seen or experienced a consistent movement of spiritual multiplication. It can feel mysterious, challenging, and overwhelming. But that should not prevent us from taking steps of faith to see disciples multiplying their faith.

As leaders, we must cast vision and create space for students to share their faith and disciple others. Cru has created an array of transferable tools that can help in this process. Students can be trained to share their story, communicate the Gospel, and disciple others in their faith.

2) My Disciples Are Too Immature to Spiritually Multiply.

This can be a difficult belief to overcome, especially for those of us who work with teenagers. Middle and high school students can often be a bit unpredictable as their brains develop and they grow in valuable life experience. But we know from experience that students can, in fact, be powerful leaders and influencers. In recent years, we have seen massive student-led movements related to climate change, gun violence, and racial injustice, just to name a few. Surely, these same students are capable of leading spiritually as well. It may not always look exactly as we would do it (more on that in a minute), but if we challenge students and give them the support they need, they are capable of incredible things. We simply have to give them the opportunity!

3) It Is Just Easier to Do It Myself.

This challenge can be particularly difficult to overcome. Empowering others to multiply can be difficult and time consuming. Sometimes, things will not go as planned. Things can get messy and unpredictable. It can be easy to believe, “No one else can do this as well as I can.” And you know what? Those thoughts may actually be true, in part!

But if we fail to empower others and embrace spiritual multiplication, our movements will remain stunted in their growth and lacking in influence and power. The end result will never reach beyond our own limited capacity. I wonder how often Jesus witnessed a disciple struggle through a task which He could have accomplished faster, easier, or better. And yet, He allowed His disciples to serve, fail, learn, and try again, and we should do the same.

It is only through spiritual multiplication that we have any hope of reaching our goal to build spiritual movements everywhere, so that everyone knows someone who truly follows Jesus!

The key is intentional planning with a relaxed atmosphere.

Game 1: Famous Couples

Choose an even number of participants and prepare a list of famous couples ahead of time, such as Luke Skywalker and Princess Leia or Romeo and Juliet. Write each name on a 3×5 card and as students enter, tape the name of one character on their back without letting them see it.

Each student may ask up to three yes or no questions per person to figure out who they are. They must also take turns answering questions when asked. The goal is to discover their identity and find their matching partner as quickly as possible. Continue until everyone is matched.

Game 2: The Dating Game

If you don’t have a lot of couples for this game, you could call it the “Best Friend Test” and have them do best friends instead. However, considering this party is about romantic relationships it is obviously better to have romantic couples playing.

This game is similar to the Best Friend Test you’ve probably seen on TikTok or shows like The Circle, or the old Newlywed game. (If you haven’t seen them, check them out). One person answers questions first, then their partner tries to guess what they said.

One partner leaves the room while the questions are asked. The partners in the room write the answers down. Then they come back, hear the same questions, and try to match their partner’s answers. Each correct match earns a point. The pair with the most points wins a prize.

The questions are light, funny, and all about how well you actually know the other person.

Dating Game Questions

For the girls (guys leave the room):

Which ice cream flavor best describes your relationship right now: Vanilla, Rocky Road, Peaches and Cream, or Tutti Frutti?
On your first date, which animal was he most like: Turtle, Kitten, Tiger, or Octopus?
How long have you been going out?
What is the most sentimental gift he has given you?

For the guys (girls leave the room):

Which Disney character would she say best describes you: Mickey Mouse, The Beast, Goofy, or Winnie the Pooh?
What song is “your song”?
What did you do on your first date?
What is her favorite perfume?
Which Valentine’s gift would she most like: candy, flowers, or a kiss?
What outfit is she wearing right now?

Optional non-gender questions

What is their go-to fast food order?
What song would they put on if they needed a hype boost?
What stresses them out faster than it should?
If they had a free day, how would they spend it?

What is something they are secretly really good at?

While relationships matter deeply to us, they also expose one of our biggest fears, the fear of not being truly loved.

Relationship Talk

Overview

The relationship talk should be short, clear, and serve as a natural bridge to the gospel. Valentine’s Day provides an easy entry point into the idea that everyone is searching for love and meaningful relationships, yet few of us have good models of what lasting love looks like.

This talk introduces the idea that there is a kind of love that lasts, a love that does not depend on performance or appearance, and that love is found in God.

Introduction

Begin with a funny or embarrassing dating story to lower defenses and help students relate.

The Talk

Relationships take a lot of time and energy, whether with parents, friends, coworkers, or romantic partners. While relationships matter deeply to us, they also expose one of our biggest fears, the fear of not being truly loved.

Psychologists often describe our greatest need as the need to love and be loved. At the same time, our greatest fear is that if people really knew us, they would reject us. Because of this, many of us wear masks and show only what we think others want to see.

Even people who care about us deeply can disappoint or reject us when we do not meet their expectations. That pain leaves us asking what real love actually looks like.

There are three common types of love people experience:

“I love you if…” love, which is conditional on behavior.
“I love you because…” love, which is based on appearance, popularity, or performance.
“I love you, period.” love, which is unconditional and unchanging.

What we truly long for is the third kind of love.

One Who Loves No Matter What

That kind of love exists, and it comes from God. God loves people for who they are, not for how they perform or what they offer. He invites us into a real relationship with Him where His love is constant and secure.

From here, transition clearly into the gospel and explain how students can have a relationship with God and experience His unconditional love.

Comment Cards

Use a comment card to collect name, address, phone number, school, and grade. Include simple response options for students who received Christ, want more information, or want to get involved with your campus ministry.

Next Step

Plan your Valentine’s Day outreach early and involve student leaders in every step so more students can experience authentic relationships and hear the gospel in a welcoming environment.

Partnering with Other Ministries to Reach Your Campus

Groups like Cru, Young Life, and FCA each have their own strengths and strategies. Students connect with them for different reasons—it’s not “one size fits all.” We love and respect every group that’s helping students know Jesus. We’re on the same team, not in competition.

Here are a few ministries we often serve alongside:

Fellowship of Christian Athletes (FCA) – Students gather in “huddles” led by coaches, giving athletes a chance to live out their faith through the sports they love.
Young Life – Leaders invest deeply in relationships, earning the right to be heard before sharing the gospel.
Church Youth Groups – Churches are a vital part of every community. Many youth leaders volunteer at schools or visit during lunch to connect with students. Cru isn’t a church—we partner with local churches to help students get plugged in.
Christian Clubs – Many campuses have Christian Clubs focused on prayer, fellowship, and Bible study. They’re often inward-facing rather than outreach-focused.

Cru’s Approach

We share Christ as soon as we have the chance, then build a network of small group Bible studies. We train students to share their faith—through group outreaches, personal conversations, and larger gatherings.

Why This Matters on Your Campus

When you are starting or growing a ministry, ask, “Who is already here?” Sometimes a group has been serving for years. Sometimes no one is reaching that school yet. Often there is room for more than one group to thrive because no single ministry connects with every student.

If another group is already present, the best move is to connect. Grab coffee with their leader, ask questions, learn what has been working, and listen for their challenges. Your posture matters. Come in as an ally, not a rival.

“We’re not in competition; we’re on the same team.”

Stepping Onto a Campus With Other Ministries

If you launch Cru where another ministry exists, remember these things:

Speak well of them in front of students.
Avoid scheduling conflicts when possible.
Focus on students they are not already reaching.
Be willing to partner for events or outreaches.

The goal is not to win students to your ministry. The goal is to help them grow in Jesus.

How to Start the Conversation

Approaching another leader can feel awkward. Keep it simple:

Ask how their group is doing at that school.
Learn which students they connect with best.
Share your heart for students and where Cru could help.
Look for ways to collaborate rather than compete.

You may be surprised how often these conversations lead to friendship and partnership.

A Simple Way to Explain Cru

When someone asks what Cru is about, you can say:

Cru is a network of student disciples who see their school as a mission field. We help students grow in their faith through small groups, training conferences, and mission opportunities locally and around the world.

When it comes down to it, no single ministry can reach every student—but together, we can make a much greater impact. Each group brings unique strengths, connections, and opportunities to the table. By cheering each other on, looking for ways to partner, and sharing a heart for teenagers to know and follow Jesus, we multiply our effectiveness. When ministries work side by side instead of in separate lanes, schools see more of Christ’s love, more students hear the gospel, and more lives are transformed for eternity.

Sydney’s Story

From Grief to Purpose: Finding God in the Storm

Growing up in a Christian home, she always knew about Jesus, but her relationship with Him didn’t feel personal until tragedy struck in eighth grade. Transitioning from homeschooling to public school had already pushed her out of her comfort zone, and anxiety loomed as she struggled to find her place. Then, during the fall of 2020, both her parents contracted COVID. While her mom recovered, her dad’s condition worsened, leading to months of uncertainty. She vividly remembers the day he left for the hospital and the long, heartbreaking journey that followed. Despite moments of hope, her dad passed away on February 20th, 2021. At just 13 years old, she faced the devastating reality of losing her father—a loss that shook her world and her faith.

In the midst of that grief, she began to see God’s hand at work. During sleepless nights and moments of overwhelming sorrow, God surrounded her with people who cared—friends, family, and a community that embodied His love. Though the pain of loss didn’t disappear, she found comfort in the truth that this life is not the end. Inspired by Paul’s words about eternity, she started to see her father’s passing as a reminder of the hope we have in Christ. That hope spurred her to action. On a family mission trip to Thailand, she met students leading Cru groups at their schools, and the seed was planted to start something similar back home. Despite initial uncertainty, God provided resources, opened doors, and brought others alongside her to launch Cru at her school—a ministry that has been thriving for nearly a year now.

"Anxiety loomed as she struggled to find her place."

Her story is one of resilience, faith, and transformation. Through unimaginable grief, she discovered the depth of God’s love and the strength found in trusting Him. The loss of her dad deepened her desire to share Jesus with others, knowing firsthand how essential His presence is in life’s hardest moments. Cru has given her a platform to do just that—to tell others about the God who redeems brokenness and uses ordinary people to do extraordinary things. Her journey reminds us that while pain is inevitable, God is sovereign, faithful, and able to bring beauty from ashes.
