1 John 4:7-9

Beloved, let us love one another, for love is of God; and everyone who loves is born of God and knows God. He who does not love does not know God, for God is love. In this the love of God was manifested toward us, that God sent His only begotten Son into the world, that we might live through Him. 

Love is a decision and not a feeling, which is why we have to decide to love one another. Our reactions to bad situations in love set us apart as Christians. Being born again helps us tap into the love nature of God because God is love. Jesus is our earthly example of love dying for our sin nature so we may live the nature of God…the nature of love. The devil has no power against love.
