Ephesians 3:14
14For this cause, I bow my knees to the Father of our Lord Jesus Christ,
“For this cause” picks up the mystery and the suffering: Paul kneels. Doctrine turns into prayer, not into a lecture only.
Access with confidence (v. 12) looks like bowed knees. Grace that opened the way also teaches the church to ask, not to swagger.
The apostle’s posture matches the Father’s majesty. Insight into the mystery produces intercession.
Even bold access is worship. Paul does not leverage revelation; he kneels under it and asks the Father to do in the church what only God can do.
