Ephesians 3:19

17 That Christ may dwell in your hearts by faith; that ye, being rooted and grounded in love,

18 May be able to comprehend with all saints what is the breadth, and length, and depth, and height;

And to know the love of Christ, which passeth knowledge, that ye might be filled with all the fulness of God.

20 Now unto him that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us,

21 Unto him be glory in the church by Christ Jesus throughout all ages, world without end. Amen.

Do read the surrounding verses too, because the context often says more than a single verse.
