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!

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.

The Six Milestones Every Student Needs to Grow in Faith

Why These Milestones Matter

If we are not careful, students can float through our ministry without ever taking real steps forward. They might show up every week, but never really grow or take ownership of their faith. Milestones give us a simple, clear map for helping them keep moving. They help us answer the question, “What’s next for this student?” and give students the courage to take that step.

When we guide students from milestone to milestone, we are not just helping them stay involved. We are helping them grow into strong, confident followers of Jesus who are ready to lead and influence others.

1
Share Christ with a Student Who Doesn’t Know Jesus

Before anything else, a student needs the chance to hear the good news of Jesus in a clear and personal way. This is where it all begins. Many teenagers have never heard the gospel explained in full, even if they have been around church. Take the time to share about God’s love, our need for forgiveness, and the hope we have in Christ. The first step in their journey is not about them sharing their faith — it is about them hearing it for the first time.

Lead a Student Through Their First Follow-Up

When a student says yes to Jesus, it is just the start of something new and exciting. The first follow-up meeting is where you can help them understand what it means to walk with God daily. It is also a chance to build trust and start a discipleship relationship. This step anchors their new faith and helps them grow instead of drifting away.

3
Help a Student Understand the ministry of the Holy Spirit

Helping students understand the Holy Spirit is a game-changer. Too often, new believers try to live the Christian life in their own strength, and it leaves them frustrated. Teaching them about the Spirit-filled life shows them how to depend on God’s power for both living and sharing their faith. This is when students start to realize that God is not just calling them to do hard things — He is empowering them to actually do them.

First Evangelism Experience

Many students have never had the chance to talk about their faith with someone who doesn’t know Jesus. Taking them out to share, whether on campus, at an event, or in the community, changes that. At first, they might feel nervous, but once they see God working through them, it can be life-changing. That moment when a student realizes, “God just used me to help someone understand the gospel” — that is the spark that often leads to a lifetime of ministry.

Challenge to a Cru Training Event

There is something powerful about getting students away from their normal routine and into an environment filled with worship, biblical teaching, and friends who are chasing after Jesus. Conferences give them the space to grow, hear from God, and take big steps of faith. The bus ride there might be full of nerves, but the ride home is usually buzzing with stories of what God did. Over and over again, we have seen students return from these events ready to lead and make a difference.

Challenge to Spiritual Leadership on Campus

Teenagers are capable of more than they realize. The world constantly challenges them to step up in sports, academics, and clubs, but sometimes the church forgets to ask them to lead in ministry. Giving students real leadership opportunities — leading a Bible study, speaking at a meeting, planning an outreach — unlocks their potential and sets an example for younger students. Over time, this creates a culture where leadership is expected and contagious.

Wrapping It Up

These milestones are not a checklist to rush through. They are a pathway to help students grow, one step at a time. Every student you know is somewhere on this journey. Your role is to encourage them, challenge them, and walk alongside them as they take the next step. The goal is not just to build a ministry — it is to build students who live on mission for Jesus for the rest of their lives.

The Priceless Project: Impacting Girls in Public Schools

The Priceless Project is a powerful small-group resource designed especially for girls, offering a safe, encouraging space to talk about identity, value, and purpose. It’s already making a difference in public schools, giving students a chance to connect, grow, and be reminded of their worth.

One of its greatest strengths is flexibility. The Priceless Project comes in two versions:

  • A Bible study version for church, youth group, or Christian school settings
  • A public school version with the same strong themes but without Scripture references — making it ideal for campuses that might not allow explicitly faith-based content

The public school version can be a great way to get in the door on a campus that’s difficult to access. It allows you to mentor a group of girls who need it, build relationships with them, and meet real emotional and social needs in a way that schools welcome.

Why use The Priceless Project?

  • Creates a safe, respectful space for girls to share and be heard
  • Meets real emotional and social needs in public schools
  • Builds leadership and peer-to-peer mentoring skills
  • Easy to use, with free resources and an app for facilitators
  • Proven track record in schools through partnerships with teachers and administrators
