Ephesians 3:12

Boldness. Gr. parresia, “freedom of speech” (see on Acts 4:13).

Access. See on ch. 2:18. Adam had that free intercourse with God at first, but, having lost it, he hid himself among the trees of the garden, because he could no longer face God with frankness and a clear conscience. The effect of redemption is to restore to man a new and bold access to God without fear or restriction, and without the need of any intermediaries such as priests or saints, or ritual. God is immediately accessible to the trusting soul, through the merits of Christ.

The faith of him. Meaning, doubtless, our faith in Him. We come to Christ in the first instance by faith, and we continue, by faith, to live the life that is called for. We can come to God with boldness only on the basis that we have faith in Christ as our mediator. He has been the only One to bridge the gulf that has separated man from God since the entrance of sin (Isa. 59:1, 2).
