v 17 Then Christ will make his home in your hearts as you trust in him. Your roots will grow down into God’s love and keep you strong. 18 And may you have the power to understand, as all God’s people should, how wide, how long, how high, and how deep his love is.
19 May you experience the love of Christ, though it is too great to understand fully. Then you will be made complete with all the fullness of life and power that comes from God.
