Our Power: Spirit-Filled Living

In this powerful sermon titled 'Our Power: Spirit-Filled Living,' Tim Keller unpacks 2 Peter 1:3–11 to reveal the transformative potential of the Christian life. He emphasizes that spiritual growth is not a matter of self-effort but is made possible by the divine power of God, who has implanted His own 'DNA'—the Holy Spirit—into believers. This divine nature enables radical, organic change, countering the cultural myth that people can't truly change. Keller stresses that growth is gradual, not instantaneous, using metaphors like a newborn baby and an acorn growing into an oak tree to illustrate how lasting transformation requires time and patience. He also highlights that spiritual growth is essential, not optional—true faith inevitably produces fruit in character and conduct. The sermon then turns practical, identifying three essential disciplines: intentional time with God through prayer and Scripture (the 'way of conversing'), vulnerability in authentic Christian community (the 'way of exchange'), and perseverance through suffering (the 'way of acceptance'). Ultimately, Keller argues that all growth is fueled by remembering the gospel—the costly grace of Jesus Christ who bore our sins and was forsaken so we would never be forgotten. This remembrance is the heart of spiritual vitality and the foundation for enduring hope and joy.
