1 John 4:20

20 If we say we love God, but hate others, we are liars. For we cannot love God, whom we have not seen, if we do not love others, whom we have seen.

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 There is no fear in love; perfect love drives out all fear. So then, love has not been made perfect in anyone who is afraid, because fear has to do with punishment.

19 We love because God first loved us.

20 If we say we love God, but hate others, we are liars. For we cannot love God, whom we have not seen, if we do not love others, whom we have seen.

21 The command that Christ has given us is this: whoever loves God must love others also.
