What does the Spirit do? The Spirit does a lot of things. It’s astonishing. If you really go back into the Old Testament you’ll see the Spirit was a creator. The Spirit is a teacher, and we’re going to see that the Spirit has three main ministries in the life of a Christian.
Those three main categories are: The Spirit regenerates us (which means he is the agent of being reborn), the Spirit sanctifies us (which means he gradually turns us more and more into the likeness of Christ in our character), and thirdly, the Spirit anoints us with power. The Spirit of God makes God real. The Spirit of God mediates the presence of Jesus Christ. So you don’t just know about him, but you sense you’re in his presence.
This sermon was preached by Rev. Timothy Keller at Redeemer Presbyterian Church on April 29, 1990. Series "Growth in Christ, Part 2". Scripture: Romans 8:15-11.

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.
This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on November 9, 2003. Series: The Necessity of Belief. Scripture: Acts 16:13-34.

A Woman, a Slave and a Gentile

The biggest problem people have in believing in God is probably the problem of evil and suffering. 
In the Greek imagination, the voyage was a metaphor for your life’s journey, and a storm was a metaphor for the evil and suffering and tragedies that come upon us. In this passage in Acts, Luke is in a boat, and he includes this account to teach us about the problems of evil and suffering.
Let’s take a look at what he teaches under three headings: 1) the paradox of the storm, 2) the product of the storm, and 3) the presence in the storm.

Stay With the Ship

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 exclusive than the claim of religious relativism, 3) this exclusive claim led to a transformation of identity, and 4) this exclusive claim led to the most inclusive human community the world had ever seen.

No Other Name

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 gospel: 1) the cultural, 2) the intellectual, and 3) the personal.
This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on October 19, 2003. Series: The Necessity of Belief. Scripture: Acts 17:16-34.
