No man hath seen God at any time. If we love one another, God
dwelleth in us. (_Ib._ iv. 12.)
God is love; and he that dwelleth in love dwelleth in God, and God
in him. (_Ib._ iv. 16.)
If a man say, I love God, and hateth his brother, he is a liar: for
he that loveth not his brother whom he hath seen, how can he love
God whom he hath not seen. (_Ib._ iv. 20.)
