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.

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.

Whenever God turns to you, if you believe in him, all he sees when he looks at you is complete beauty and sweetness. Jesus Christ offered himself up and fulfilled all of the obligations we owe God, so he has completely satisfied God. God sees nothing and senses nothing but sweetness when he regards you.

But you still live in a world twisted and broken by sin. And you have to deal with the realities of that. Therefore, there’s always a negative. And Ephesians 5:3-7 tells the negatives: there are prohibitions, limits, warnings. There are no exceptions to them. 

We must see both the positive and the negative: 1) the positive is that Jesus has fulfilled the law, and 2) for the negative, there are three categories of no’s: no covetousness, no foolish talking, and no sexual immorality.

If you look at the particulars Christian teachings, the particulars don’t look that different from many other ethical systems. The difference is that Christianity is never interested in moral behavior simply as moral behavior. In every instance, putting on the new self means to remember your identity.

Being a Christian is ultimately about being melted with spiritual understandings of who you are now that Jesus Christ has said, “You are my beloved child,” of who you are now that the Holy Spirit has come in and said, “I now live within your heart.” Ephesians 4 is an amazingly multifarious passage on what the Christian lifestyle really is. And the purpose of this passage is to show how we can put off the old self and put on the new. 

Let’s look at anger and forgiveness. We’ll look at anger to see 1) suppression or denial of anger is wrong, 2) anger is sometimes required, 3) there are sinful forms of anger, and 4) if you can’t forgive, it’s because you haven’t sensed his forgiveness.
