<p>3:14- see on Eph. 1:15.</p><p><i>For this cause I bow my knees to the Father</i>- This resumes the train of thought from &quot;this cause&quot; in :1. The intervening verses, as noted there, are a parenthesis. What we now read until the &quot;Amen&quot; in :21 is a unique transcript of Paul's prayer for them, said on his knees, and also mixing praise with worship; for to bow the knee is an idiom for praise as well as the prayer of request. Paul uses the same words in writing of how every knee shall bow to God at the day of judgment (Rom. 14:11); but he lived in prayer now as he would before the day of judgment. That was exactly the sense of his idea of being &quot;confident&quot; both in prayer now and the day of judgment in the future- see on :12. Our attitude in prayer to God now will be out attitude at the day of judgment.</p>
