Whom we preach, warning every man, and teaching every man in all wisdom; that we may present every man perfect in Christ Jesus:
Preach, х katangellomen (G2605)] - 'announce.'
Warning ... teaching. "Warning" leads to repentance, refers to conduct, and is addressed to the heart. "Teaching" leads to faith, refers to doctrines, and is addressed to the intellect: the two heads of evangelical teaching.
Every ... every man - without distinction of Jew or Gentile, great or small (Romans 10:12-13). The repeated "every man" teaches ministers to deal with individual consciences.
In all wisdom - with all the wisdom in our method of teaching that we possess (Alford). But Colossians 1:9, and Colossians 3:16, favour Estius-the wisdom communicated to those being taught: keeping back nothing, but instructing all in the perfect knowledge of the mysteries of faith, the true wisdom (cf. 1 Corinthians 2:6-7; 1 Corinthians 12:8; Ephesians 1:17).
Present - what Christ does, Paul does (note, Colossians 1:22): at Christ's coming.
Every man. Paul is zealous lest the false teachers should seduce one single soul at Colosse. Each should be zealous for himself and his neighbour. Even one soul is of incalculable value.
Perfect in Christ - the element in living union with whom alone each can find perfection; perfectly instructed (Ephesians 4:13) in doctrine, and full grown in faith and practice. "Jesus" is omitted in 'Aleph (') A B Delta G f g. C, Vulgate, have it.
