19 We love, because *4:19 Because God bestowed on humanity a free will, man is not forced to love Him, but rather consciously and freely chooses the response he makes to God’s love.He first loved us. 20 If anyone says, "I love God," and hates (works against) his [Christian] brother he is a liar; for the one who does not love his brother whom he has seen, cannot love God whom he has not seen.
