YLT(i)
19 we—we love him, because He—He first loved us;
20 if any one may say—`I love God,' and his brother he may hate, a liar he is; for he who is not loving his brother whom he hath seen, God—whom he hath not seen—how is he able to love?
21 and this is the command we have from Him, that he who is loving God, may also love his brother.
