Let Your Yes Be Yes

August 25, 2023

As we look at the hard sayings of Jesus, we see in this passage that Jesus gives us a radical principle of truthfulness. 

The whole Bible is built on covenants, public promises, observed words. So what does Jesus mean when he says to let your “yes” be “yes”? He can’t mean you can’t take oaths. What he does mean is actually something almost the opposite, that if you think you can separate and create levels of truthfulness, you’re wrong. Everything is observed. Every yes and every no is an oath. 

Jesus is teaching us 1) the importance of truthfulness, 2) the nature of truthfulness, and 3) how you become a person of integrity.

This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on February 14, 1993. Series: Hard Sayings of Jesus (1993). Scripture: Matthew 5:33-37.

We’re looking at the most strange, enigmatic, perplexing things Jesus ever said. This is one of them. People always blink a bit when they read it.  But here, Jesus is actually teaching us about power to change. He’s telling us something extremely practical.  Even though it’s an enigmatic passage, Jesus is basically saying three things: 1) There are many ways to change, 2) if you use any way but Jesus, you’ll be worse off than before, and 3) Jesus is the only one who can give you the power to change thoroughly and permanently. This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on February 7, 1993. Series: Hard Sayings of Jesus (1993). Scripture: Luke 11:14-26.

When Jesus is asked by his disciples, “Lord, teach us to pray,” he tells them a story and puts forth an approach that runs against common sense and against what other religions say about prayer. In the story, a man who’s in bed at midnight gives bread to another man who’s knocking and asking. Jesus says the man gives the bread not because the other man is his friend but because of the man’s boldness. Other ways to translate the word Jesus uses include shamelessness, rudeness, discourtesy, impertinence, and impudence. That’s what Jesus says is a model for our prayer. “Pray like that,” he says. “Bother God.”  Why should we pray this way? Jesus gives the answer: 1) it’s a way to judge our hearts today, and 2) it’s a way to actually live our lives tomorrow in a different way. This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on January 31, 1993. Series: Hard Sayings of Jesus (1993). Scripture: Luke 11:5-13.

If Jesus was a pastor, I don’t think his church would’ve grown very fast. Any leader of a movement wants to make it easy for people to enter. But Jesus acts in a completely different way. People come and say, “I want to join up,” and Jesus says, “Get back. Think.”  In Luke 9, Jesus does this because the three men clearly don’t understand what they are asking for. Therefore, if we take a look at how Jesus answers them, we’re going to learn a great deal about what it means to follow Jesus.  What does it mean to be a follower of Jesus? This text shows us 1) that to follow Christ is to enter the kingdom, 2) that we need to understand the hardness of the kingdom, and 3) that we need to understand the greatness of the kingdom. This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on January 24, 1993. Series: Hard Sayings of Jesus (1993). Scripture: Luke 9:57-60.

Sometimes when you read Jesus’ teachings, you feel like you’ve gotten on a horse that’s much too big and much too fast for you. When you read what Jesus says in Luke 12, you have nothing but lightning and blood, but in the center of this teaching is the most wonderful thing a human heart can hear. In this text, we learn two things: we learn about the divisiveness of Jesus caused by his self-centered teaching, and we learn about the agony of Jesus caused by his self-denying love. It may be surprising to many of you to see what he says, but you don’t know the real Jesus unless you understand his divisiveness and the constant agony and pressure under which he labored every minute of his ministry. Let’s look now at these two things: 1) the divisiveness of Jesus, and 2) the agony of Jesus. This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on January 17, 1993. Series: Hard Sayings of Jesus (1993). Scripture: Luke 12:49-53.

In Matthew 11, Jesus talks about the kingdom of God, and he uses the word “violence.” That’s what the Greek word means. There’s no way around it.  The context is Jesus telling us about John the Baptist, who realized the kingdom of heaven is real. Then Jesus says the kingdom of heaven comes with violence. This bothers us. Isn’t this Jesus? Isn’t this the one who said, “turn the other cheek?” Yes. That’s the reason why Jesus uses this term. Jesus is a communicator. He knows by saying this you’re going to be startled. You’re going to say, “What does that mean?”  Let’s cooperate with him. Let’s ask, what is this holy violence? Let’s look at 1) what it’s not, 2) what it is, and 3) why we need it. This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on June 3, 1992.

Jesus said an awful lot of hard things. And in the story of the rich young ruler, Jesus says two hard things: he says our understanding of riches and our understanding of moral goodness are wrong. The rich young ruler is not only rich, but he’s also a man of exquisite moral character. Yet, Jesus sends him away. Jesus turns our common notions about wealth and goodness on top of their heads and he gives us new ones—ones that are explosively in contradiction with what the world thinks, but ones that, if we obey them, have the power of God exploding in our midst. Let’s look at these two principles. Jesus tells us 1) something new about wealth and 2) something new about moral goodness. This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on June 3, 1992. Series: Hard Sayings of Jesus (1993). Scripture: Mark 10:23.

In this cultural moment, when our non-Christian friends look at the Christian faith, they often see a history of racism, an anti-intellectual mindset, homophobia, and the denigration of women.  It's tempting to think that the best thing Christians can do is batten down the hatches and cling on for dear life, while the waves of secularization wash over us. But if that's what we think, I believe we've got it all wrong. When we look more closely at each of these devastating roadblocks, they become signposts to Christ.  I believe we have an opportunity before us. But there are four things we need to do. We must reclaim 1) diversity, 2) the university, 3) morality, and 4) sexuality. But we must do all these things with humility and not by watering the scriptures down, but by lapping them up.

For a person to go from no faith to faith it takes at least four things.  There has to be 1) sustained attention, 2) some attraction, 3) a demonstration, and 4) an explanation.  I’m going to give a couple ideas on three of these four things.

The name reflects our conviction that the gospel changes everything in life. In 1989 Dr. Timothy J. Keller, his wife and three young sons moved to New York City to begin Redeemer Presbyterian Church.
