Ephesians 3:16-19

That He would grant you, according to the riches of His glory, to be strengthened with might through His Spirit in the inner man,
that Christ may dwell in your hearts through faith; that you, being rooted and grounded in love,
may be able to comprehend with all the saints what is the width and length and depth and height—
to know the love of Christ which passes knowledge; that you may be filled with all the fullness of God.

Mark 12:29-31

Jesus answered him, “The first of all the commandments is: ‘Hear, O Israel, the LORD our God, the LORD is one. And you shall love the LORD your God with all your heart, with all your soul, with all your mind, and with all your strength.’ This is the first commandment. And the second, like it, is this: ‘You shall love your neighbor as yourself.’ There is no other commandment greater than these.”
