Summary

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. This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on May 26, 1991. Series: Christian Lifestyle. Scripture: Ephesians 5:8-14.

0:00.0	Welcome to Gospel in Life.
0:06.1	True transformation isn't about adopting a set of rules.
0:09.7	It's about a heart changed by the gospel.
0:12.2	This month, Tim Keller explores how Christianity is not just an ethical system, but a supernatural transformation.
0:26.0	Thank you. but a supernatural transformation. We've been moving through the book of Ephesians,
0:28.5	and I'm just going to take you through a little bit of this,
0:33.6	enough to get us ready to receive the Lord's supper.
0:38.0	Please turn to Ephesians 5, and let's start maybe at verse 7.
0:42.9	I'm just going to read from verse 7 to 14, a new section.
0:51.1	For you were once darkness, but now you are light in the Lord.
0:55.0	Live as children of light, for the fruit of the light consists in all goodness, righteousness, and truth.
1:02.8	And find out what pleases the Lord, have nothing to do with the fruitless deeds of darkness,
1:07.3	but rather expose them. For it is shameful even to mention what the disobedient do in secret.
1:14.3	But everything exposed by the light becomes visible.
1:17.8	For it is light that makes everything visible.
1:21.4	This is why it is said, awake, oh sleeper, and rise from the dead, and Christ will shine on you. Here ends the reading of
1:30.9	God's word. You know, by spending as much time as we have in Ephesians, we started Ephesians
1:39.4	chapter 4 about how many months ago, a long time ago. The reason we're moving so slowly is partly to
1:47.8	show you the richness of this all. But on the other hand, the richness of the book is great,
1:55.7	but sometimes you need to stand back and let me just show you something. The book of Ephesians is roughly
2:02.5	divided into the first three chapters. It has a lot to do with Paul laying out his understanding
2:10.1	of God's calling to us. Ephesians 1, 2, and 3 tells us that God's great purpose in history is to call us to himself through Christ,
