Having reviewed his readers" blessings in Christ, Paul next prayed that they would appreciate and appropriate these good things in their own lives. He moved from benediction to intercession. Ephesians 1:15-23 are one sentence in the Greek text, as are Ephesians 1:3-14. Intellectual understanding is one thing, but it is also important that we use this knowledge to come into intimate relationship with God. That is what Paul prayed for in this prayer.

"For a healthy Christian life today it is of the utmost importance to follow Paul"s example and keep Christian praise and Christian prayer together. Yet many do not manage to preserve this balance. Some Christians seem to do little but pray for new spiritual blessings, apparently oblivious of the fact that God has already blessed them in Christ with every spiritual blessing. Others lay such emphasis on the undoubted truth that everything is already theirs in Christ, that they become complacent and appear to have no appetite to know or experience their Christian privileges more deeply."
