Love is the visible attribute of an invisible God.

"No one has ever seen God; but if we love one another, God lives in us and his love is made complete in us."    1 John 4:12

In other words, even though no person has ever actually seen God the Father, but we are able to see God's character when we love one another. Remember that God is love (1 John 4:8); in this, the love of God was manifested among us, so, when we walk in love, God lives in us in the perfect way. Thus, although we can't actually see God, we can see his character in our love for each other (and in his love for us). Indeed, Romans 5:8 tells us that God demonstrates his own love for us in this: While we were still sinners, Christ died for us. Furthermore, Jesus said that we, his disciples, will be known by our fruit: By their fruit you will recognize them  (Matthew 7:16,20).  Galatians 5:22 tells us what that fruit is: The fruit of the Spirit is love ... Thus, we are known by our love—love for one another and love for God, it is so important for us,  we walk in love, because love is the visible attribute of an invisible God. Hallelujah, Amen God bless
