16So we have come to know and to believe the love that God has for us. God is love, and whoever abides in love abides in God, and God abides in him. 17By this is love perfected with us, so that we may have confidence for the day of judgment, because as he is so also are we in this world. 18There is no fear in love, but perfect love casts out fear. For fear has to do with punishment, and whoever fears has not been perfected in love. 19We love because he first loved us.
