Colossians 3:12

The apostle proceeds to exhort to mutual love and compassion: Put on therefore bowels of mercy, Col 3:12. We must not only put off anger and wrath (as Col 3:8), but we must put on compassion and kindness; not only cease to do evil, but learn to do well; not only not do hurt to any, but do what good we can to all. I. The argument here used to enforce the exhortation is very affecting: Put on, as the elect of God, holy and beloved. Observe, 1. Those who are holy are the elect of God; and those who are the elect of God, and holy, are beloved - beloved of God, and ought to be so of all men. 2. Those who are the elect of God, holy and beloved, ought to conduct themselves in every thing as becomes them, and so as not to lose the credit of their holiness, nor the comfort of their being chosen and beloved. It becomes those who are holy towards God to be lowly and loving towards all men. Observe, What we must put on in particular. (1.) Compassion towards the miserable: Bowels of mercy, the tenderest mercies. Those who owe so much to mercy ought to be merciful to all who are proper objects of mercy. Be you merciful, as your Father is merciful, Luk 6:36. (2.) Kindness towards our friends, and those who love us.

the elect of God--There is no "the" in the Greek, "God's elect" (compare Rom 8:3; Th1 1:4). The order of the words "elect, holy, beloved," answers to the order of the things. Election from eternity precedes sanctification in time; the sanctified, feeling God's love, imitate it [BENGEL]. bowels of mercies--Some of the oldest manuscripts read singular, "mercy." Bowels express the yearning compassion, which has its seat in the heart, and which we feel to act on our inward parts (Gen 43:30; Jer 31:20; Luk 1:78, Margin). humbleness of mind--True "lowliness of mind"; not the mock "humility" of the false teachers (Col 2:23; Eph 4:2, Eph 4:32).
