Gospel in Life
with Tim Keller
The Battle for the Heart
Friday, February 20, 2026
To be a holy person is not what people popularly think it is these days. In modern English we often use the word “holy” to mean “holier than thou”—inaccessible, condescending, and self-righteous. Or at best, people will think of a holy person as somebody who keeps all the rules.
But holiness is not about keeping all the rules. Holiness is an attitude of the heart in which you look at God and you say, “Use me.” Therefore, to be holy means more than just to give him your mind; you have to give him your life. In 1 Peter 1, there is a contrast shown between a life without God and a holy life. And this contrast shows us a depiction of a holy life.
These verses show us that 1) a life without God is ignorant, but a life of holiness integrates the thought and the life, 2) a life without God is an imitative life, but a holy life is an examined life, and 3) a life without God is a life of slavery without authority, but a holy life is a life of freedom under authority.
This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on October 31, 1993. Series: Splendor in the Furnace: 1 Peter, Part 1. Scripture: 1 Peter 1:13-16.
