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.
4:20. If any man say: I love God, and hateth his brother; he is a liar. For he that loveth not his brother whom he seeth, how can he love God whom he seeth not?
4:21. And this commandment we have from God, that he who loveth God love also his brother.
1 John Chapter 5
Of them that are born of God, and of true charity. Faith overcomes the world. Three that bear witness to Christ. Of faith in his name and of sin that is and is not to death.
5:1. Whosoever believeth that Jesus is the Christ, is born of God. And every one that loveth him who begot, loveth him also who is born of him.
Is born of God… That is, is justified, and become a child of God by baptism: which is also to be understood; provided the belief of this fundamental article of the Christian faith be accompanied with all the other conditions, which, by the word of God, and his appointment, are also required to justification; such as a general belief of all that God has revealed and promised: hope, love, repentance, and a sincere disposition to keep God's holy law and commandments.
