We live in a fragmented culture. There’s no consensus about the big questions of what’s right and wrong and true. Jeremiah is a prophet in this same situation—he lived and wrote in a fragmented culture. 
One of the challenges of a fragmented culture is living in the cafeteria of different worldviews, religions, and systems of thought. It’s typical to respond by saying, “I don’t think anybody has the answer.” But Jeremiah shows us that this very statement is ignorant of how the heart works.
Jeremiah shows us that we need to see three things about the human heart: 1) the radical faith of every heart, 2) the radical flaw in every heart, and 3) the radical cure for every heart.

Have you in this modern world learned how to become happy and stay happy?
I hope you don’t think that’s a trivial question. Because if you read the psychology books, the urban planning books, the biochemistry books, the political science books, they’re really about this problem: we’re not happy. How can we be happy? 
The Bible has always said the issues that make you happy or unhappy are profoundly cosmic and spiritual. In Psalm 1, we see 4 principles: 1) happiness is possible, 2) happiness is fundamental, not superficial, 3) happiness can never be found directly, and 4) happiness is something you choose.
This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on September 12, 1993. Series: Modern Problems; Ancient Solutions. Scripture: Psalm 1.

The Search for Happiness

Jesus, in Matthew 18, uses a word for conversion that means to turn completely around and face in a whole new direction. That’s a perfect image of what Christian conversion really is. 
Christian conversion is a radical inner transformation. But it’s not so much a replacing of what you are as a re-facing of what you are. Your temperament doesn’t go away; your culture doesn’t go away. But everything you are is now lived on a whole new basis.
The case study of Cornelius the centurion teaches us four important facts. Christian conversion comes 1) through God’s initiative, 2) through the challenge to religion, 3) through the transformation of the Holy Spirit, and 4) through the words of the gospel.

Converted by the Spirit

Christianity was originally never understood as a set of teachings that one took on. Christianity was a power that took you up. It completely turned you inside out, transformed you from the inside. 
The classic example is the conversion of Paul. Paul was an abusive, violent zealot. He went from someone who was deeply unhappy and restless to someone who was utterly unflappable, absolutely content. How? A radical, deep conversion. 
We all need to know how to live deeply converted lives. And though Paul’s conversion is dramatic, it shows three things involved in every conversion: 1) an untame God, 2) a stubborn fact, and 3) a radical relationship.

Converted by the Resurrection

Conversion is a radical change of life. And in its early days, Christianity grew through conversions. It spread so rapidly that it changed a hostile society completely.
What does it mean to become a Christian? By looking at the conversions in Acts, we can see what Christianity really is. 
In this passage, the conversion of an Ethiopian, we learn three things: 1) who converts, 2) the context of conversion, and 3) the key instrument conversion uses.
This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on November 16, 2003. Series: The Necessity of Belief. Scripture: Acts 8:26-40.

Converted by the Cross

Christianity was born into a culture that was every bit as resistant and unsympathetic to its claims as ours is. So how did its message come into the lives of people and actually change them? 
In Acts, we have more case studies of conversion than anywhere else in the Bible. And in this passage, Luke chooses three to show us both how incredibly different and yet how incredibly similar Christian conversions can be. 
What does it mean to be a Christian, and how do you become a Christian? 1) Lydia is a case of the gospel for the religious, 2) the slave girl is a case of the gospel for the oppressed, and 3) the jailer is a case of the gospel for the secular.
