Ephesians 3:19

17 so that Christ may dwell in your hearts through faith. Then you, being rooted and grounded in love,

18 will have power, together with all the saints, to comprehend the length and width and height and depth

of the love of Christ, and to know this love that surpasses knowledge, that you may be filled with all the fullness of God.

20 Now to Him who is able to do so much more than all we ask or imagine, according to His power that is at work within us,

21 to Him be the glory in the church and in Christ Jesus throughout all generations, forever and ever. Amen.

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