Colossians 2:10

Verse 10. And ye are complete in him. Having no need, for the purposes of salvation, of any aid to be derived from the philosophy of the Greeks, or the traditions of the Jews. All that is necessary to secure your salvation is to be found in the Lord Jesus. There is a completion, or a filling up, in him, so as to leave nothing wanting. This is true in respect (1.) to the wisdom which is needful to guide us; (2.) the atonement to be made for sin; (3.) the merit by which a sinner can be justified; and (4.) the grace which is needful to sustain us in the trials, and to aid us in the duties of life. See Barnes "1 Co 1:30".
