1 John 4:9-13

By this the love of God was revealed in us, that God has sent His only Son into the world so that we may live through Him.

In this 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 also ought to love one another.

No one has ever seen God; if we love one another, God remains in us, and His love is perfected in us.

By this we know that we remain in Him and He in us, because He has given to us of His Spirit.
