Do you know God? If you did, then you would love others in the way that He loves you. Love is of God: therefore, if you don’t know how to love as God loves then you don’t know Him. You really can’t define love without first knowing God, and you certainly can’t show true love without a personal relationship with Him. It’s like a person who thinks that a fast-food burger is the greatest food out there, but only because they have never been introduced to good, quality food. You might exercise something that you call love, but until you know the love of God, you haven’t even tasted of what love truly is.

1 John 4:7-11
7. Beloved, let us love one another: for love is of God; and every one that loveth is born of God, and knoweth God.
8. He that loveth not knoweth not God; for God is love.
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.
11. Beloved, if God so loved us, we ought also to love one another.
