This verse is the application of the foregoing discourse, in which you have an exhortation to the practice of two great duties. The one is peace, or peaceableness; the other is mutual edification. He had persuaded before to peace with all men, Romans 12:18; and here he speaks more especially of peace and concord amongst brethren: see 2 Corinthians 13:11 Ephesians 4:3 Colossians 3:15 1 Thessalonians 5:13 Hebrews 12:14. This peace is very necessary, and Christians should endeavour all things that will promote it, and avoid all things that will obstruct it. And they must not only live peaceably, but profitably one with another. They should build one another up in grace and knowledge.
