Note 1 at Eph. 1:15: Paul is not praying for these Ephesians because they are in terrible shape. He commends them for their faith in Jesus and love unto all the saints. Yet, there was more that Paul wanted them to receive.

There is more to being saved than just getting our sins forgiven. The new birth ushers us into the kingdom of God which is infinitely greater in wonder and benefits than our finite minds can comprehend. But to the degree that we do begin to understand how God's kingdom works and apply our lives to it, we can experience heaven here on earth (see note 32 at Mt. 6:10, p. 134).

This doesn't happen automatically and it doesn't happen all at once. We are progressively changed as we renew our minds (see notes 6-9 at Rom. 12:2, pp. 825-826). All Christians are the same in their born-again spirit (see note 3 at Mt. 26:41, p. 507) but there many different levels of understanding and accompanying victory which we manifest in our lives.

Therefore, Paul prays that these Ephesians would come to experience in their flesh what is already theirs in their spirit. This prayer is still valid for every believer today. You can personalize this prayer and receive the same wisdom and revelation that Paul was praying for the Ephesians to receive.
