Every healthy church is built not only by the strength of its programs but by the depth and maturity of its people. Programs may organize activity, but only people carry life. God’s greatest strategy has never been structures or systems—it has always been people. From Abraham who believed, to Moses who led, to the disciples who followed Jesus, God has always chosen ordinary men and women and shaped them through His Word, empowered them by His Spirit, and sent them to accomplish His mission.
When God wants to transform a city, He doesn’t start with a plan—He starts with a person. He forms hearts before He builds ministries. That is why the true measure of a church’s strength is not in how busy it is, but in how deeply its people are being formed into the likeness of Christ.
1. Understanding Key Leaders in the Church
In every generation, God raises key leaders—men and women whose lives influence others and shape the spiritual direction of the church. In the New Testament, Paul calls them “faithful people who will be able to teach others also” (2 Timothy 2:2). These are not merely people with titles or talents, but servants with character, calling, and capacity to carry the mission of God forward.
In the context of the church, key leaders are:
- Spiritual influencers who reflect Christ’s character and values in their daily lives.
- Multipliers who help others grow in faith, not just maintain programs.
- Culture carriers who embody and spread the heart of the house—living examples of the church’s mission and values.
Key leaders are the strategic backbone of a local church. They determine not only how far the church can grow, but how deep it can sustain its growth. The vision of a church can only move as fast as the people who carry it, and its capacity is defined by the maturity, unity, and spiritual health of its leaders. When key leaders are strong in character, clear in conviction, and aligned in calling, the whole church moves with strength and clarity. But when leadership is shallow, fragmented, or dependent on a few, even a great vision will struggle to become reality. That is why building key leaders is not optional—it is essential to multiplying impact and ensuring longevity in the life of the church.
In IFGF Semarang, we believe that key leaders are the bridge between vision and reality. Building key leaders, therefore, is not an organizational task—it is a spiritual calling. It’s how we prepare the next generation to continue God’s work with excellence, integrity, and grace.
2. The Biblical Foundation of Key Leadership
When we talk about key leaders in the New Testament, we often think of apostles like Peter or Paul. Yet the early church also had local leaders who played crucial, strategic roles in nurturing believers, strengthening churches, and expanding the mission—leaders who were not part of the Twelve, but were indispensable to the Kingdom’s advance.
One remarkable example is Barnabas, whose name means “son of encouragement” (Acts 4:36). Though not one of the apostles, Barnabas became a key leader whose character, faith, and relational wisdom shaped the early church in profound ways. He exemplifies the kind of leader every local church needs—steady, Spirit-filled, and kingdom-minded.
Barnabas: A Biblical Pattern for Key Leaders
- He built bridges, not walls.
When Saul (later Paul) first came to Jerusalem after his conversion, the believers were afraid of him. It was Barnabas who stepped in, introduced Paul to the apostles, and vouched for the authenticity of his faith (Acts 9:26–27).A key leader brings connection and reconciliation. He sees beyond someone’s past to their potential in Christ. - He developed others rather than dominating them.
Barnabas recognized God’s hand on Paul and willingly took a supporting role so that Paul’s ministry could flourish (Acts 11:25–26). Instead of clinging to prominence, he empowered others to rise.A key leader doesn’t need the spotlight; he builds platforms for others to shine. - He represented the church with maturity and integrity.
When the church in Antioch needed guidance, it was Barnabas who was sent from Jerusalem to assess and strengthen the growing movement (Acts 11:22–24). His leadership was marked by wisdom, discernment, and encouragement, leading to great growth in the church.A key leader stabilizes the church through maturity and faith, ensuring growth that is both spiritual and sustainable. - He modeled grace in conflict.
Even when Barnabas and Paul disagreed over John Mark (Acts 15:37–39), Barnabas chose restoration over rejection. Later, Paul himself would affirm Mark’s usefulness (2 Timothy 4:11)—a testament to Barnabas’ grace-centered leadership.A key leader values people over perfection and believes in second chances.
Phoebe — The Trusted Servant and Kingdom Financier (Romans 16:1–2)
Role: Deacon of the church in Cenchreae, likely the one who carried Paul’s letter to the Romans.
Why she’s strategic: Phoebe represents leadership through service and stewardship. She was both a servant (diakonos) and a patron (prostatis), supporting the mission with generosity, influence, and trustworthiness.
Leadership qualities:
- Trustworthy in responsibility: Paul commended her to the church in Rome.
- Supportive of mission: She used her position and resources to advance the gospel.
- Respected by apostles: Her partnership was essential to Paul’s ministry.
Pattern for the local church today: Key leaders may not preach from the pulpit but play a vital role in supporting, resourcing, and sustaining the church’s mission.
Priscilla and Aquila — The Mentoring Couple (Acts 18:24–26; Romans 16:3–5)
Role: A husband-and-wife team who hosted a house church and mentored Apollos.
Why they’re strategic: They model discipleship leadership in everyday life—teaching, hosting, and multiplying disciples from their home.
Leadership qualities:
- Relational mentoring: They “explained the way of God more accurately” to Apollos.
- Hospitality and teamwork: Their home was a base for the church.
- Reproducible model: They represent leadership rooted in relationships and community life.
Pattern for the local church today: Key leaders are not only on stage—they are found in homes, guiding others in truth and love.
3. Building Key Leaders in IFGF Semarang
IFGF Semarang’s mission—“People is our mission: connect with God, make disciples”—is the heartbeat of leadership development. Building key leaders means developing people who live out this mission with excellence, integrity, and love.
Here’s how we can build them intentionally:
A. Identify the Faithful
Look for those who show Faithfulness, Availability, Submissiveness, and Teachability (F.A.S.T.)—the essential traits of emerging leaders in the church.
- Faithfulness — They are consistent in character and dependable in responsibility, showing integrity even in small things (Luke 16:10).
- Availability — They make time to serve God and people, demonstrating that leadership is not about convenience but about calling.
- Submissiveness — They walk in humility and alignment with spiritual authority, understanding that true leadership begins with learning to follow (Hebrews 13:17).
- Teachability — They remain open to feedback, correction, and growth, recognizing that leadership is a continual process of formation in Christ.
Practical step: Observe potential leaders in iCare groups, Sunday teams, or ministry settings—those who serve with the right heart, not just the right skill. Look for people who are responsive, humble, and eager to grow under guidance, because those who submit well today will lead well tomorrow.
B. Invest in Their Formation
Building key leaders doesn’t happen by accident — it requires intentional investment. Spiritual formation is the foundation of all true leadership. Jesus Himself modeled this: He didn’t simply gather crowds; He formed twelve people through daily life together — teaching them truth, correcting their attitudes, shaping their character, and empowering their faith. Leadership development, therefore, is not an event but a journey of transformation.
Every leader in the local church must be intentionally formed before they are publicly positioned. Skill can be developed quickly, but character takes time — and only intentional discipleship can produce the kind of leaders who lead with both wisdom and integrity.
At IFGF Semarang, we believe formation must be both structured and relational. It’s not enough to have information; people need impartation — a transfer of life, values, and heart. Formation happens best when truth is lived out in community and modeled by leaders who walk closely with those they mentor.
This intentional formation takes place through several key environments:
- Discipleship Journey: Come → Grow → Serve → Lead.
This pathway provides a clear process for every believer to move from being a follower to a disciple, from serving to leading. Each stage develops new dimensions of faith, maturity, and responsibility. - Masterclasses and Leadership Training.
These sessions combine biblical principles with practical ministry skills, equipping leaders not only to serve effectively but also to think biblically, lead teams, and solve real problems with godly wisdom. - One-to-One Mentoring Relationships.
Leadership formation requires proximity. Growth happens not just in classrooms but through life shared — walking together, asking questions, and learning through experience. Mentoring allows seasoned leaders to model faith, integrity, and perseverance, creating a culture of reproduction rather than dependency. - Ministry Opportunities (On-the-Job Training).
Real leadership development happens when people are entrusted with real responsibility. Through serving in ministries — whether in iCare groups, Sunday services, or special events — emerging leaders learn to carry weight, manage pressure, and develop practical and technical skills. As they serve, they learn not only how to do ministry, but why they do it — to glorify Christ and build His church.
Intentional formation means creating a rhythm of learning, reflection, and practice. It’s about walking patiently with potential leaders until they begin to walk confidently with God. When we invest time, attention, and heart into people, we are not just building volunteers — we are building vessels for Kingdom impact.
Leaders are not found, they are formed.
C. Impart the Culture
Every church carries a unique spiritual DNA—a set of values, attitudes, and convictions that shape how its people live, serve, and lead. At IFGF Semarang, that DNA is life-giving, relational, and Spirit-empowered. It reflects the heart of Jesus, who came not to condemn the world but to bring life (John 10:10).
A healthy church culture doesn’t emerge by accident—it must be intentionally imparted. Programs can transfer knowledge, but only people can transfer culture. Culture is not primarily taught in classrooms; it is caught through consistent example, language, and atmosphere. Key leaders become living carriers of the church’s heart. They don’t just serve under the vision—they embody it, so that wherever they lead, the same spirit flows.
To impart culture effectively, leaders must live with clarity, consistency, and connection:
- Clarity — Know the core values deeply. You cannot impart what you don’t understand.
- Consistency — Model the same values in every setting—whether on stage, in meetings, or in private conversations. Culture is reinforced not by slogans, but by steady behavior.
- Connection — Culture is transmitted relationally. People learn what the church truly values by observing how leaders treat them, especially in moments of stress, failure, or disagreement.
In IFGF Semarang, our culture can be summarized in three powerful contrasts that shape how we lead:
- Grace over judgment — We choose to build people up rather than tear them down. We believe correction without condemnation brings transformation.
- Relationship over religion — We prioritize connection before correction, believing that discipleship happens best in the context of authentic relationships.
- Transformation over performance — We value genuine growth in Christ more than outward appearance or activity. We celebrate changed lives, not just successful events.
Imparting culture means weaving these values into the language, rhythm, and practices of every ministry. It requires repetition, storytelling, and shared experiences.
Practical steps:
- Use leadership gatherings to teach and remind teams why we do what we do—not just how.
- Encourage senior leaders to spend time with emerging leaders so the heart of the house is transferred, not just the system.
When culture is consistently imparted, alignment happens naturally. People begin to speak the same language, serve with the same heart, and pursue the same mission. Over time, the atmosphere of the church becomes unmistakable—a place where grace flows freely, relationships thrive deeply, and transformation happens daily.
Culture is not taught—it is caught.
4. Who Are the Key Leaders in a Local Church?
Key leaders play a strategic role both in the present and the future of the church. They ensure that the mission is not only declared from the pulpit but also demonstrated in daily ministry. Through their faithfulness and leadership, the church moves from intention to impact—growing in health, alignment, and effectiveness. Without key leaders, vision remains an idea; with them, vision becomes reality. They are the bridge between where the church is today and where God is leading it tomorrow.
1. Core Leadership Team — Those Who Carry the Vision
These are the people who work closely with the Senior Pastor to guard the mission, model the culture, and align the ministries.
They often include:
- Pastors and ministry heads (e.g., Worship, Kids, Youth, iCare, Operations)
- Key coordinators overseeing multiple ministries
Their role:
To translate vision into action—ensuring that every ministry reflects the same DNA, values, and direction. They are the custodians of the church’s heartbeat.
2. Mid-Level Leaders — Those Who Multiply People
These are the leaders of leaders, often called coaches, team leaders, or iCare leaders. They lead small groups, ministry teams, or volunteer units.
Their role:
To shepherd and develop others. They are close enough to the people to disciple, but experienced enough to build others into leaders.
They are the “Barnabas-type” leaders — encouragers, trainers, and connectors — who multiply the ministry at the relational level.
In IFGF Semarang, these include:
- iCare group leaders and CTL
- Ministry coordinators (worship, hospitality, media, kids, etc.)
- Volunteer captains
“And the things you have heard from me among many witnesses, entrust to faithful people who will be able to teach others also.” — 2 Timothy 2:2
3. Emerging Leaders — Those Who Are Being Formed
Every healthy church identifies potential key leaders—faithful and teachable people who are still learning but show spiritual maturity and commitment.
Their role:
To grow in responsibility through intentional discipleship and ministry opportunities. They are the future of the leadership pipeline—the next generation of iCare leaders, team heads, or pastors in training.
They might currently be:
- Faithful volunteers
- iCare members who serve consistently
- Young leaders showing initiative and humility
“Whoever can be trusted with very little can also be trusted with much.” — Luke 16:10
4. Support and Functional Leaders — Those Who Sustain the House
These are leaders who may not be front-facing, but they keep the church functioning excellently. Their leadership is often expressed through administration, finance, communication, production, or operations.
Their role:
To enable ministry to flow smoothly, creating structure and systems that support the vision. They carry organizational leadership that sustains the life and efficiency of the church.
“Each part does its work…so that the whole body grows and builds itself up in love.” — Ephesians 4:16

Closing Reflection
Many churches struggle to grow or sustain impact—not because their vision is unclear, but because they fail to identify and develop key leaders. A church can only move as far as its leaders can carry it. That’s why leadership development is not a luxury—it’s a necessity.
If we desire to see lasting fruit, we must be willing to invest time, resources, and finances in people. This means intentionally sending them to missions, exposing them to conferences, and even providing scholarships and mentoringso they can grow in capacity and conviction.
When we invest in leaders, we are investing in the future of the church. For every key leader we raise, the reach of the gospel extends further, and the heart of Christ is multiplied through their lives.
“If you want your ministry to last for a season, build programs.
If you want it to last for generations, build people.”
