Ephesians 3:16-18

.. that He would grant you, according to the riches of His glory, to be strengthened with might through His Spirit in the inner man, 17 that Christ may dwell in your hearts through faith; that you, being rooted and grounded in love, 18 may be able to comprehend with all the saints what is the width and length and depth and height [of the love of Christ].

Romans 5:5

5 Now hope does not disappoint, because the love of God has been poured out in our hearts by the Holy Spirit who was given to us.
