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?

1 John 4:20 Meaning and Commentary

1 John 4:20

If a man say I love God, and hateth his brother
Than which profession nothing can be more contradictory, not black and white, or hot and cold in the same degree:

he is a liar;
it is not truth he speaks, it is a contradiction, and a thing impossible:

for he that loveth not his brother whom he hath seen;
his person, which might have drawn out his affection to him; and something valuable and worthy in him, which might have commanded respect; or his wants and distresses, which should have moved his pity and compassion:

how can he love God whom he hath not seen?
it cannot be thought he should; the thing is not reasonable to suppose; it is not possible he should; (See Gill on 1 John 4:12).

1 John 4:20 In-Context

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.

19 Let us therefore love God: because God first hath loved us.

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?

21 And this commandment we have from God, that he who loveth God love also his brother.
