Charles Ellicott Commentary Colossians 4:2-4

"Continue stedfastly in prayer, watching therein with thanksgiving; withal praying for us also, that God may open unto us a door for the word, to speak the mystery of Christ, for which I am also in bonds; that I may make it manifest, as I ought to speak." — Colossians 4:2-4 (ASV)

Compare the almost exact parallel in Ephesians 6:18-20, and see Notes there.

A door of utterance.—Compare a similar phrase in 1 Corinthians 16:9; 2 Corinthians 2:12. There, however, the opened door is the door of external opportunity; here the “door of utterance” is the removal of all internal impediments to preaching.
