I heard it said once that love is the most popular topic in music. Love, love, love, love..... God is love. 1John 4:8, 4:16. To answer the question of "do you know Love?" We have to say do you know God? Without Jesus Christ you don't. He is the Way, the Truth and Life to Love. He modeled love from the cradle to the cross. I believe it was Athanasius that said "God became man so we may become God." If an Atheist loves it because he is acting like God. God is on display. He may not know God but the world may see God through him. When one finds love nothing else matters. Tell the Lord you need love. You will not find it anywhere else or love anyone else.
