Here are a few of many, many verses of scripture talking about his love.
Ephesians 3: 16-19
I pray that from the treasures of his glory he will empower you with inner strength by his Spirit, so that the Messiah may live in your hearts through trusting. Also I pray that you will be rooted and founded in love, so that you, with God's people, will be given strength to grasp the breadth, length, height and depth of the Messiah's love, yes, to know it, even though it is beyond all knowing, so that you will be filled with all the fullness of God.
