1 John 4:11

⁹ In this was manifested the love of God toward us, because that God sent his only begotten Son into the world, that we might live through him.

¹⁰ Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins.

Beloved, if God so loved us, we ought also to love one another.

¹² No man hath seen God at any time. If we love one another, God dwelleth in us, and his love is perfected in us.

¹³ Hereby know we that we dwell in him, and he in us, because he hath given us of his Spirit.

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