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.

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 th ..read more

Christianity was born into a society hostile to its claims. And the claim that was most revolting to that society is also what our society sees as the most repugnant: the shocking claim that salvation is found in no one else. It’s critical to realize this claim was as implausible in the Greco-Roman world as it is in ours. The Roman Empire was every bit as religiously pluralistic as our society, if not more. If they were as revolted as we were, why did so many believe it?  Acts 4 shows us four important things: 1) the claim was an implication, not arrogation, 2) the claim is no more exclus ..read more

The culture in which Christianity was born was every bit as skeptical of the claims of Christianity as ours is. But the case for Christianity was made so strongly that skeptical people believed in numbers so great that it changed the entire Roman culture.  There’s no better place to see the case that changed the whole Roman Empire than the book of Acts. Within it, there are a number of spots where Paul or Peter make the case, including this famous spot where Paul speaks to the intellectual elites on Mars Hill in the Areopagus.  This text shows three aspects to the persuasive power of ..read more

It’s a simple fact that in the Greco-Roman world, the claims of Christianity were found every bit as implausible, if not more, than people find them now. So why did so many people believe?  Fortunately, we have a case study in Theophilus. How does a cultured, intellectually sophisticated person living in a culture that’s hostile to the basic claims of Christianity come to believe Christianity is true? The answer in a nutshell: the resurrection.  Whether we already believe or aren’t sure we believe, because of the resurrection we can know three things: 1) the truth is out there, 2) th ..read more

We’re not at home. We live in a world that doesn’t sustain or support the deepest needs of our hearts. Martin Heidegger (a fascist sympathizer) and Karl Marx (the father of Communism) were very different, prominent thinkers; yet, they both agreed that we can’t understand the human condition without the concept of alienation. Of course, that immediately raises the question, why wouldn’t we feel at home here?  The prophet Jeremiah gives us a lot of insight: 1) why we long for a home, 2) how we can get home, and 3) what life there will be like. This sermon was preached by Dr. Timothy Keller ..read more

In a culture where people really don’t know who they are and what life’s about—in a fragmented culture like ours—the fastest way to still feel good about ourselves is romance. It’s the ultimate philosophical narcotic.  “I don’t know what life is about, but when I’m with her or him, I feel somehow life is significant.” Do you see? It’s an end run. That’s the reason why in all fragmented cultures, romance and sex and marriage can either be the ultimate fatal detour or a clue to how to find your way home.  Jeremiah tells us about 1) an incredible offer: the ultimate lover; 2) the proble ..read more

Jesus Christ says not just “I was resurrected,” but “I am the resurrection.” Present tense. He comes after his resurrection with his arms full of newness.  I don’t know why we get into gift-giving at Christmas—I think we ought to be getting into it at Easter. Because as soon as Jesus Christ shows up risen from the dead, he is giving out all kinds of gifts of newness.  Let’s look at these gifts and divide them into two parts: 1) there is the gift of faith, and 2) there are all the rest of the gifts that come out of that. This sermon was preached by Dr. Timothy Keller at Redeemer Presb ..read more

We’ve been looking at the life of Jesus and we come now to the risen Jesus. At the end of the gospel of Luke, the risen Jesus does four things that change the lives of his disciples forever. And because he’s the risen Jesus, he can do the very same things for us right now.  Jesus 1) answers the doubts of their minds by arguing with them, 2) satisfies the needs of their hearts by eating with them, 3) reforges the direction of their lives by sending them, and 4) shows them his hands and his feet. This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on April 20, 200 ..read more

The night Jesus was betrayed has a theme: darkness, night. Right in the middle of the passage, Jesus makes an odd statement: “But this is your hour—when darkness reigns.” What that must mean is the physical darkness is a representation of something deeper.  There’s a darkness that blinds the eyes, and then there’s a darkness that blinds the heart and the mind and the soul. It’s a spiritual darkness. This is the thing Jesus came to deal with. Because he came to deal with it, there’s a solution for it.  There are three incidents that happened in the physical dark. The first two tell us ..read more
