The second part is practical. Chaps. 3, 4. The duties on which the apostle insists come mainly under two general heads. The first is that of a heavenly temper of mind growing out of their resurrection with Christ who sits at the right hand of God, and who shall appear again to receive his disciples to himself, that they also may appear with him in glory. In view of this animating hope he exhorts the Colossians to put away all the sins belonging to their former state of heathenism. Chap. 3:1-8. The second is that of mutual love and harmony arising from their union with each other in Christ, whereby they have been made one holy body, in which outward distinctions are nothing “but Christ is all and in all.” On this ground they are urged to cultivate all the graces of the Spirit, the chief of which is love, and faithfully to discharge, each one in his station, the mutual duty which they owe as husbands and wives, as parents and children, as masters and servants. Chaps. 3:9-4:1.

The epistle closes with notices of a personal character intermingled with salutations (verses 7-18).

(1) Some think it was a letter written by the church of Laodicea to Paul, and forwarded by him to the Colossians. (2) Others understand it of an epistle of Paul to the Laodiceans (perhaps forwarded along with the three epistles now under consideration) and which the Colossians were to obtain from Laodicea. This is the most probable supposition. On the attempt to identify this
