Introduction to Colossians

This epistle was sent because of some difficulties which arose among the Colossians, probably from false teachers, in consequence of which they sent to the apostle. The scope of the epistle is to show, that all hope of man's redemption is founded on Christ, in whom alone are all complete fulness, perfections, and sufficiency. The Colossians are cautioned against the devices of judaizing teachers, and also against the notions of carnal wisdom, and human inventions and traditions, as not consistent with full reliance on Christ. In the first two chapters the apostle tells them what they must believe, and in the two last what they must do; the doctrine of faith, and the precepts of life for salvation.
