3:12-17 We must not only do no hurt to any, but do what good we can to all. Those who are the elect of God, holy and beloved, ought to be lowly and compassionate towards all. While in this world, where there is so much corruption in our hearts, quarrels will sometimes arise. But it is our duty to forgive one another, imitating the forgiveness through which we are saved. Let the peace of God rule in your hearts; it is of his working in all who are his. Thanksgiving to God, helps to make us agreeable to all men. The gospel is the word of Christ. Many have the word, but it dwells in them poorly; it has no power over them. The soul prospers, when we are full of the Scriptures and of the grace of Christ. But when we sing psalms, we must be affected with what we sing. Whatever we are employed about, let us do every thing in the name of the Lord Jesus, and in believing dependence on him. Those who do all in Christ's name, will never want matter of thanksgiving to God, even the Father.
17. Literally, "And everything whatsoever ye do … do all," &c.; this includes words as well as deeds.
in the name of the Lord Jesus—as disciples called by His name as His, seeking His guidance and help, and desiring to act so as to gain His approval (Ro 14:8; 1Co 10:31; 2Co 5:15; 1Pe 4:11). Compare "in the Lord," Col 3:18, and "Christ is all," Col 3:11.
God and the Father—The oldest manuscripts omit "and," which seems to have crept in from Eph 5:20.
by him—Greek, "through Him" as the channel of His grace to us, and of our thanksgiving to Him (Joh 14:6, end).
