Albert Barnes Commentary Ephesians 3:12

"in whom we have boldness and access in confidence through our faith in him." — Ephesians 3:12 (ASV)

We have boldness. The word here used—parrēsian—means, properly, boldness of speaking, 2 Corinthians 7:4; John 7:26; Acts 4:13, 29, 31.

Here it seems to mean "freedom of utterance;" and the idea is that we may come to God now in prayer with confidence through the Lord Jesus. See Hebrews 4:16.

And access. See the notes on Ephesians 2:18.

By the faith of him. By faith in him. The sense is that we may now come confidently and boldly to the throne of grace for mercy in the name of the Redeemer. Boldness is not rashness, and faith is not presumption; but we may come without hesitating, and with an assurance that our prayers will be heard.
