A Detour to Ephesians 4
Important things in the Bible are often repeated or rephrased throughout as a means to emphasize their importance. The latter half of Ephesians 4 is no different.
Ephesians 4:17-32 generally expresses similar sentiments and critiques as Romans 1 - describing the condition of Gentiles whilst in paganism. While Romans tends to look at it from God's perspective, Ephesians reiterates this same condition from a more man-centered perspective. We're exhorted to put off our old self (v.22) and put on our new self, washed in the blood of Christ and renewed by the grace of God (v.23-24).
I'd like to put some extra emphasis on the latter half, verses 25-32. This is a significant problem that I have had over the years, understanding the nature of this passage and how to rightly apply it even amongst the outpouring of sinfulness in my own heart. It is a good reminder to all of us that we are to be above the pettiness that we see exhibited by the world.
25 Therefore, having put away falsehood, let each one of you speak the truth with his neighbor, for we are members one of another.
26 Be angry and do not sin; do not let the sun go down on your anger,
27 and give no opportunity to the devil.
28 Let the thief no longer steal, but rather let him labor, doing honest work with his own hands, so that he may have something to share with anyone in need.
29 Let no corrupting talk come out of your mouths, but only such as is good for building up, as fits the occasion, that it may give grace to those who hear.
30 And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption.
31 Let all bitterness and wrath and anger and clamor and slander be put away from you, along with all malice.
32 Be kind to one another, tenderhearted, forgiving one another, as God in Christ forgave you.
