The Bible tells us faith begins with thinking. The Bible says faith requires and stimulates the profoundest thinking and reasoning. You cannot be a Christian without using your brain to its uttermost. 

Nowadays, we’re told by our culture from the time we’re very little that the big questions—what is real, what is right and wrong, and what we should be living for—are questions for the philosophers. We’re taught that the important things are standard of living, career, appearance, and psychological needs. 

Hebrews 11 shows us three aspects about faith: 1) that thinking leads to faith, 2) how thinking leads to faith, and 3) whythinking leads to faith. 

This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on September 18, 1994. Series: The Nature of Faith. Scripture: Hebrews 11:1-7.

What is faith? What is it made of? How do you know if you have it? How do you lose it? How do you get it back? Hebrews 11 deals with all of these things through specific personal case studies of men and women who wrestled with issues of faith.

I would suggest that it’s the easiest to understand the parts of faith as three layers, one of which comes first, then the others resting upon it. But the reality is it’s more complex than that. If you look hard enough at any one of these aspects, the other two are contained in the one. Yet all three are absolutely critical if we’re going to understand faith.

Faith 1) begins with understanding, 2) which leads to conviction, but 3) completes itself always in commitment.

One mark of a supernaturally changed heart is a changed attitude and view of races and cultures. 

In social relations, grace-changed Christians use their power to serve, not exploit. We’re going to look at this by looking at a dispute that happened in the church of Rome, and by comparing it to another dispute.

These passages show us 1) the problems that culture poses, 2) the solutions, true and false, and 3) how we get the power to implement the true solution.

Some people say there’s a cultural crisis of integrity. 

For example, Volkswagen was revealed to have deliberately used software designed to lie about emissions. It was a failure of integrity from one of the biggest corporations in the world. And some of you may be yawning, thinking that’s just the way things are. But the Bible says a supernaturally changed heart rejoices with the truth.

Let’s talk about 1) how important integrity is, 2) how you practice integrity, and 3) how you can become people of integrity. 

This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on June 19, 2016. Series: What We Are Becoming: Transforming Love. Scripture: Ephesians 4:14-15, 25-32.

When the Greeks and Romans met the early Christians, one of the first things that surprised them was how Christians handled suffering. 

Christianity brought into the world a view and a way of handling suffering that the world had never seen. It was one of the evidences of a supernaturally changed heart. And in Romans 8, a passage that looks at all the benefits of salvation, we learn a lot about suffering.

Romans 8 shows us 1) the unique Christian view of suffering, 2) the unique resources we get to face suffering, and 3) how we can make those resources our own.

What are the characteristics of a supernaturally changed heart?

You can be very moral and active in church and still be an incredibly impatient, bitter person. So we’re looking at what Paul says are the marks of a supernaturally changed heart. And for this, Romans 12 is an explosive passage. 

Let’s look at what this passage says about 1) patience and graciousness in life in general, and 2) love and forgiveness in the face of mistreatment.

This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on May 8, 2016. Series: What We Are Becoming: Transforming Love. Scripture: Romans 12:9-21.

Most of us know how to restrain a life. We start to get in trouble, so we change. But when the consequences go away, we snap back the way we were. 

Human nature without supernatural intervention is like a rubber ball that’s squished, but when the pressure is off, it snaps right back. The rubber ball was constrained. It wasn’t actually changed or reshaped. 1 Corinthians 13 is about how you actually change, about how you get a supernaturally changed heart.

What is the supernaturally changed heart? Let’s take a look at 1) two things it is not and 2) what it is.

There is nothing that beggars your own sense of wisdom than to study what the Bible says about divine wisdom.

Ephesians 5 tells us a lot about wisdom. And it shows us that biblical wisdom puts God in the center in a way that develops three aspects of wisdom.

We see in these verses 1) why we need to walk in wisdom, and 2) what it means to walk in wisdom.

This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on June 9, 1991. Series: Christian Lifestyle. Scripture: Ephesians 5:11-17.

Ephesians 5 talks about light and wisdom. Paul says that because you once were darkness and now are light, you should now expose works of darkness and experience the fruit of light.

Then in verse 15, Paul says that we are to walk as wise and not as fools, for the days are evil. What Paul is saying is that walking in wisdom is the way in which you expose the deeds of the darkness.

In these verses, Paul shows us 1) there are two different realms—darkness and light, 2) we are to have nothing to do with unfruitful works of darkness, but are to instead bear the fruit of the light, and 3) as one who is in the light, your job is to expose the deeds of darkness.

The essence of Christianity is arguing with yourself. What makes you an effective Christian is that you’re continually arguing with yourself, and you’re winning the argument.

Because of what Christ did, God can restore the world and restore everything if we come to him through Christ. And in Ephesians 5, Paul uses the imagery of darkness and light to argue with us about how we need to be living: “For you were once darkness, but now you are light in the Lord.” If you don’t get the verse right, you’ll never win the argument. 

To understand this, we have to understand what the Bible means when it talks about light and darkness in spiritual terms. It means: 1) God is truth, 2) God is righteousness, and 3) a mark of somebody who has crossed from darkness to light is that they become more of a servant.

Christianity is never a mechanical thing. And the church is not a morality agency—it’s a regenerating agency.

The real goal of the do’s and the don’ts in the Christian life is always character—growing into God’s holy people. The church does bring about moral behavior but, in a sense, as a byproduct. Because what the church is after is to turn people into saints, to create a kind of person.

In Ephesians 5, we learn three things: 1) your Christian faith has to include a saying no as well as a saying yes, 2) Paul explains a few critical things you must say no to (greed, foolish talking, and sexual immorality), and 3) the whole point is not to give us a list of do’s and don’ts, but the point is always to be holy.
