Ephesians 3:14

“For this cause I bow my knees unto the Father, &c.] That is, pray unto him for the perseverance of the saints; for nothing is more desirable to the ministers of Christ than that; which is the pure gift of God, and is what he has promised, and therefore should be prayed to for it; for what God has designed and promised to his people, he will be sought to; and the apostle's view might be also to stir up these saints to pray for themselves: the gesture he used in prayer was bowing the knees; a man is not tied to any particular gesture or posture in prayer, the main thing is the heart; mere postures and gestures are insignificant things with God; though where the mind is affected, the body will…”

“For this cause--Resuming the thread of Eph 3:1, "For this cause." Because ye have such a standing in God's Church [ALFORD]. bow my knees--the proper attitude in humble prayer. Posture affects the mind, and is not therefore unimportant. See Paul's practice (Act 20:36); and that of the Lord Himself on earth (Luk 22:41). unto the Father--The oldest manuscripts omit "of our Lord Jesus Christ." But Vulgate and some very old authorities retain them: Eph 3:15, "From whom," in either case, refers to "the Father" (Patera), as "family" (patria, akin in sound and etymology) plainly refers to Him. Still the foundation of all sonship is in Jesus Christ.”

“For this cause - Some suppose that this is a resumption of what he had commenced saying in Ephesians 3:1, but which had been interrupted by a long parenthesis. So Bloomfield explains it. But it seems to me more probable that he refers to what immediately precedes. “Wherefore, that the great work may be carried on, and that the purposes of these my sufferings may be answered in your benefit and glory, I bow my knees to God, and pray to him.” I bow my knees - I pray. The usual, and the proper posture of prayer is to kneel; Compare 2 Chronicles 6:13; Daniel 6:10; Luke 22:21; Acts 7:60; Acts 9:40; Acts 20:26; Acts 21:5. It is a posture which indicates reverence, and should, therefore, be assumed…”

“3:14-21 Paul closes this section (1:3–3:21) with a second prayer for his readers. The first (1:15-23) was for their spiritual understanding, the second (3:14-21) is for their spiritual growth and empowerment. 3:14 When I think of all this, I fall to my knees and pray: Paul resumes what he started to say at the beginning of the chapter (see 3:1).”
