Ephesians 3:17-19

And I pray that you, being rooted and established in love, may have power, together with all the saints, to grasp how wide and long and high and deep is the love of Christ, and to know this love that surpasses knowledge — that you may be filled to the measure of all the fullness of God.

Ephesians 1:9-10

He made known to us the mystery of his will according to his good pleasure, which he purposed in Christ, to be put into effect when the times will have reached their fulfillment – to bring all things in heaven and on earth together under one head, even Christ.
