Timothy Keller

"You want to know how to plant a successful church?" Kathy Keller said. "Find out where God is beginning a revival, and move there the month before."

Early influences. Tim Keller's path to becoming a renowned urban theologian began in small-town Pennsylvania. At Bucknell University, he encountered InterVarsity Christian Fellowship, which shaped his early understanding of evangelism and community. His time at Gordon-Conwell Theological Seminary exposed him to diverse theological perspectives, laying the groundwork for his later synthesis of ideas.

Pastoral experience. Keller's nine-year tenure at West Hopewell Presbyterian Church in Virginia provided crucial pastoral experience. This small-town ministry taught him how to connect biblical teaching with everyday life, a skill that would prove invaluable in his later urban ministry. The move to New York City to plant Redeemer Presbyterian Church in 1989 marked a turning point, challenging Keller to adapt his ministry to a highly secular, urban context.

"If you cut a person—a good minister, for example—like a tree, there should be a lot of rings. That gives that minister his own distinctive voice and perhaps really helps him listen to what God is calling him to be as a minister."

Diverse influences. Keller's theological approach is characterized by his ability to synthesize ideas from various sources. He drew inspiration from:

• Reformed theologians like Jonathan Edwards and John Calvin

• Literary figures such as C.S. Lewis and J.R.R. Tolkien

• Contemporary thinkers like Charles Taylor and Alasdair MacIntyre

Unique synthesis. This diverse range of influences allowed Keller to develop a unique theological vision that combined:

• Orthodox Reformed theology

• Cultural engagement

• Urban ministry strategies

• Intellectual rigor in apologetics

"Redeemer became a church for recovering Christians, for people who realized their dreams didn't deliver. We were searching for authentic religion."

Contextual approach. Redeemer Presbyterian Church, founded by Keller in 1989, became a model for urban ministry. Key elements of its success included:

• Contextualizing the gospel for a highly educated, secular audience

• Engaging with cultural issues and intellectual objections to Christianity

• Emphasizing both personal faith and cultural renewal

Growth and impact. The church grew rapidly, attracting both skeptics and believers. Its impact extended beyond New York through:

• Church planting initiatives

• The formation of Redeemer City to City, a global church planting network

• Keller's books and speaking engagements, which popularized his approach to urban ministry

"Evangelize as you edify, and edify as you evangelize."

Balancing act. Keller's approach to ministry sought to maintain biblical orthodoxy while engaging contemporary culture. This involved:

• Preaching that addressed both believers and skeptics simultaneously

• Addressing cultural issues through a biblical lens

• Emphasizing the transformative power of the gospel for both individual lives and society

Practical application. This gospel-centered approach manifested in:

• Sermon series that tackled difficult cultural topics

• Integration of faith and work initiatives

• Mercy ministries that demonstrated the practical implications of the gospel

"The real secret of fruitful and effective mission in the world is the quality of our community."

Community focus. Keller consistently emphasized the importance of Christian community, drawing on his experiences with InterVarsity and other influential groups. This focus was evident in:

• The small group structure at Redeemer

• Emphasis on hospitality and relational evangelism

• Integration of new believers into the life of the church

Discipleship model. Keller's approach to discipleship emphasized:

• One-on-one mentoring

• Group Bible studies

• Equipping lay leaders for ministry

"If you believe the Gospel and all its remarkable claims about Jesus and what he has done for you and who you are in him, then nothing that happens in this world can actually get at your identity."

Intellectual engagement. Keller developed a unique approach to apologetics that:

• Addressed common objections to Christianity in a winsome manner

• Drew on diverse sources, including philosophy, literature, and social sciences

• Aimed to make Christianity intellectually credible to skeptics

Key works. His apologetic approach is exemplified in books like:

• "The Reason for God"

• "Making Sense of God"

• "The Prodigal God"

"Our models of theological formation give us a firm grasp of biblical doctrine, which is indispensable, but they fail to deconstruct culture's beliefs and provide better, Christian answers to the questions of the late modern human heart."

Urban focus. Keller pioneered an approach to urban ministry that:

• Recognized the unique challenges and opportunities of cities

• Adapted traditional Reformed theology to urban contexts

• Emphasized the importance of cultural exegesis

Post-Christian adaptation. His approach acknowledged the shift to a post-Christian culture by:

• Addressing the underlying assumptions of secular worldviews

• Reframing Christian concepts for those unfamiliar with religious language

• Demonstrating the relevance of Christianity to contemporary issues

"It just blew me away. I never forgot it."

Fresh perspective. Keller's interpretation of the Prodigal Son parable, influenced by Edmund Clowney, offered a fresh perspective on the gospel that:

• Challenged both religious and irreligious people

• Emphasized God's radical grace

• Addressed the elder brother syndrome in many churches

Wide impact. This reframing of the gospel:

• Resonated with both skeptics and long-time Christians

• Became a central theme in Keller's preaching and writing

• Influenced a generation of pastors and theologians

"If the church does not identify with the marginalized, it will itself be marginalized."

Balanced approach. Keller sought to integrate social justice concerns with orthodox theology by:

• Grounding social action in biblical teaching

• Critiquing both conservative and liberal approaches to justice

• Emphasizing the connection between personal faith and social responsibility

Practical initiatives. This approach led to:

• The formation of Hope for New York, Redeemer's mercy ministry

• Engagement with issues like racial reconciliation and economic justice

• A model for other churches seeking to address social issues

"At times staff members have protested that my vision was outpacing my ability to lead it or their ability to implement it."

Growth challenges. As Redeemer grew, Keller faced significant leadership challenges, including:

• Managing a rapidly expanding staff and budget

• Navigating organizational complexity

• Balancing visionary leadership with practical management

Adaptations. Keller adapted his leadership style by:

• Delegating more responsibilities to other leaders

• Focusing on training and equipping others

• Developing a model for multi-site church growth and eventual independence

Legacy planning. Keller's approach to succession and long-term impact included:

• Developing a network of independent churches from Redeemer

• Investing in global church planting through Redeemer City to City

• Mentoring the next generation of urban ministry leaders
