4:11. My dearest, if God hath so loved us, we also ought to love one another.
4:12. No man hath seen God at any time. If we love one another, God abideth in us: and his charity is perfected in us.
4:13. In this we know that we abide in him, and he in us: because he hath given us of his spirit.
4:14. And we have seen and do testify that the Father hath sent his Son to be the Saviour of the world.
4:15. Whosoever shall confess that Jesus is the Son of God, God abideth in him, and he in God.
4:16. And we have known and have believed the charity which God hath to us. God is charity: and he that abideth in charity abideth in God, and God in him.
4:17. In this is the charity of God perfected with us, that we may have confidence in the day of judgment: because as he is, we also are in this world.
4:18. Fear is not in charity: but perfect charity casteth out fear, because fear hath sin. And he that feareth is not perfected in charity.
Fear is not in charity, etc. . .Perfect charity, or love, banisheth human fear, that is, the fear of men; as also all perplexing fear, which makes men mistrust or despair of God's mercy; and that kind of servile fear, which makes them fear the punishment of sin more than the offence offered to God. But it no way excludes the wholesome fear of God's judgments, so often recomended in holy writ; nor that fear and trembling, with which we are told to work out our salvation. Phil. 2.12.
4:19. Let us therefore love God: because God first hath loved us.
