" Ephesians 3:16–19 (NIV), which is really the charter of contemplative prayer: I pray that out of his glorious riches He may strengthen you with power through his Spirit in your inner being so that Christ may dwell in your hearts through faith. And I pray that you, being rooted and grounded 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 with the very nature of God.
