Introduction

Paul has been telling us how, as a result of what God has done for us, we should now live our lives. And one of the dominating images that he has used has been the action of walking. “Walk worthy. . .”(4:1) “No longer walk as the rest of the Gentiles
walk. . .” (4:17). And now he tells us how we should walk. We should walk in love (5:2), light (5:8), and wisdom (5:15).

Walk in Love v. 1-7

Children imitate their parents. Walking faithfully is a matter of remembering who your Father is. Are you a child of God (5:1) or a child of the enemy (5:6). There are two ways of living contrasted here – a life of giving yourself away (5:2, cf. Gal. 2:20) or a life of resenting what others haven’t given you (5:3). Christ has modeled for us self-emptying love that God has for us. This is the sweet aroma of Christ (5:2), which we become when we give ourselves away to others (2 Cor. 2:15).

Walk in Light v. 8-14

The judgment given in the last section, that no fornicator, unclean person, or covetous man will inherit the kingdom of God, comes across as pretty extreme. But now we see that this is a judgment that includes forgiveness (5:8, cf. 1 Cor. 6:11). Paul reminds the Ephesians once more that they have passed from death to life (5:14), but adds to this the image of “light.” Christians must walk in the light (cf. 1 John 1:5-10).

And light will expose the things done in darkness (5:11). This does not mean we are called to “darkness sting operations” (although we are called to confront sin – Mat. 18:15, Gal. 6:1). Light does not run from darkness, rather darkness flees from light. By being light in the world, the darkness of the world is expose or made manifest.

Walk in Wisdom v. 15-21

Again, Paul gives us two ways of living. There is a dissolute lifestyle, characterized by drunkenness, foolishness, and dissipation (5:17-18). There is a trajectory to this life. It begins with foolishness, that is giving in to not thinking about the result that your actions are causing or cultivating the habit of giving up half way through the math problem. It gives way to dissipation, that is wasting away all that you have. And it ends with a self- centered aloneness.

On the other side, we see Paul describing a pursuit of wisdom, which corresponds in a certain way to drunkenness (cf. Acts 2:13). But it is an intoxication that leads to wisdom (instead of foolishness), to a wiser use of all things (instead of dissipation), and to a deep union with your fellow saints (instead of the self-centered aloneness).

No Longer Walking as the Gentiles Walk (v. 17-19)

Because of what Christ has done for you, there is no longer any good reason for you to act like the unsaved Gentile. This is a life characterized by the futile mind, darkened understanding, alienated from God, ignorant, blind, past feeling, lewd, unclean, and greedy. But you are these things “no longer” (v. 14, 17).

As Peter tells us, you’ve spent enough time there (1 Pet. 4:1-3). Now it’s time to be done with the lusts of the world and to give ourselves to the will of God.

Put Off, Put On v. 20-24

The Christian motivation for obedience is the result of understanding who you are (1 Pet. 4:1, Rom. 6:4-7). The lusts that want to rob you of Christ are deceitful. They enslave you by telling you lies. Remembering who you are in Christ will always be one of the most powerful weapons for putting to death the works of the flesh.

But we are called to put off that old, dead man. Put him off and put on the new man in true righteousness and holiness.

The New Man v. 25-32

Remember that we have been seeing Paul continually bring up this image of a “man” or a “body” throughout Ephesians. At one moment this man is Jesus, the incarnate Son of God. But at other moments, the “man” or “body” being described is the church.

When we think of putting on the “new man,” we tend to think of private, spiritual disciplines that happen in the secret places of our hearts. But it is interesting to note the disciplines that Paul lists when we are putting on the “new man.”

Don’t lie to one another. Don’t get angry at one another. Don’t steal from one another. Instead, look for ways to give to each other. Speak with edification to one another. Get rid of bitterness and anger. Forgive one another.

These are all disciplines for living within the corporate body of Christ. The new man that we are putting on is simultaneously Christ and the Church. We shouldn’t pit the individual renewal against the corporate manifestation of this renewal.

For This Reason (v. 14-16)

Paul is entering into a conclusion for the first half of the book of Ephesians. The preceding three chapters have taught us about the new family to which we, through the Son, now belong. And Paul concludes form this that we ought to be doing two things. The first is that we ought to be worshipping God. The second is that we ought to receive the strengthening of the inner man from the Holy Spirit.

Rooted (v. 16-17)

Now Paul expands on the nature of this strengthening. First, we must constantly remind ourselves that the strengthening of the inner man is revealed in a way that only the eye of faith will see (2 Cor. 4:16-18). Second, we should note that this is a gift from God, not something that we strive to create in ourselves. Third, we should realize what the revelation of God’s glory looks like. The fear is always that God’s concern for his glory makes him a self-centered megalomaniac. But, here we see that God’s glory is revealed in his goodness to us.

That You Might Know (v. 18-19)

The aim of giving this gift is to see us have two things – a knowledge of what it is that God has done for us and, by that knowledge, a deep confidence in our salvation. God desires that we have confidence that establishes us like a try rooted deep into the earth and able to withstand great storms.

This is what happens when you meditate on God’s word daily as the man in Psalm 1 does. You become rooted, established, founded, convinced. Your meditating on the promises of God is a chance for God to argue daily your doubts out of you.

Glory (v. 20-21)

All of this is the work of God, “. . . to him who is able to do.” He is the power that works in us. This has all been a description of the work which God works. So what is left for us to do? We worship.

Paul’s Suffering is the Gentiles Glory

Paul introduces and closes this section with a reference to his being in prison specifically because of the Gentiles (v. 1 and 13). But he says that this imprisonment is good for them, it’s their “glory” (v. 13). How so?

The Mystery

The first three chapters of the book of Ephesians are packed tightly with a number of different images that Paul uses to describe our reconciliation with God. Paul describes this reconciliation as a mystery that was being unfolded (1:9-10). This means that throughout the OT this was being hinted at, but not directly said. And part of this mystery was the inclusion of the Gentiles (Eph. 3:4-6 and 9). It was clearly prophesied. And yet it was so incredible, so unthinkable that the Jews who poured over these prophecies still could not see this coming. In fact, we are told that even the angels didn’t see this coming (Eph. 3:10).

One Body

And the thing that they are brought into is one body (v. 6). Jews and Gentiles, heaven and earth, are brought together into one body. If you think about it for a moment then you start to realize that the “one body” might be more than just an image. It is actually, literally one body. It’s Jesus. Jesus is God become man, heaven reaching out to earth, life having the victory over death, sinners reconciled to God.

A Book of Mysteries

This ridiculously complex mystery was all wrapped up in this book. And you can read and read and study and study and you cannot exhaust the depth and profundity of this mystery.

A Future Mystery

The mystery that unfolded was still a mystery until it unfolded. And that means that though it was promised, it was utterly incomprehensible until that moment that it unfolded. The mystery of how God would achieve salvation through the incarnation, death, burial, and resurrection of his Son was once a mystery and is now a clear fact. But we live in the face of another mystery. Where do we go after we die? God has told us. He has made promises about it. And yet it is still a mystery. God record in the past should give us peace in trusting in this promise.
