Young's Literal Translation
Testing the Spirits
1Beloved, every spirit believe not, but prove the spirits, if of God they are, because many false prophets have gone forth to the world; 2in this know ye the Spirit of God; every spirit that doth confess Jesus Christ in the flesh having come, of God it is, 3and every spirit that doth not confess Jesus Christ in the flesh having come, of God it is not; and this is that of the antichrist, which ye heard that it doth come, and now in the world it is already. 4Ye — of God ye are, little children, and ye have overcome them; because greater is He who [is] in you, than he who is in the world. 5They — of the world they are; because of this from the world they speak, and the world doth hear them; 6we — of God we are; he who is knowing God doth hear us; he who is not of God, doth not hear us; from this we know the spirit of the truth, and the spirit of the error.
Love Comes from God
7Beloved, may we love one another, because the love is of God, and every one who is loving, of God he hath been begotten, and doth know God; 8he who is not loving did not know God, because God is love. 9In this was manifested the love of God in us, because His Son — the only begotten — hath God sent to the world, that we may live through him; 10in this is the love, not that we loved God, but that He did love us, and did send His Son a propitiation for our sins. 11Beloved, if thus did God love us, we also ought one another to love; 12God no one hath ever seen; if we may love one another, God in us doth remain, and His love is having been perfected in us; 13in this we know that in Him we do remain, and He in us, because of His Spirit He hath given us. 14And we — we have seen and do testify, that the Father hath sent the Son — Saviour of the world;
15whoever may confess that Jesus is the Son of God, God in him doth remain, and he in God; 16and we — we have known and believed the love, that God hath in us; God is love, and he who is remaining in the love, in God he doth remain, and God in him. 17In this made perfect hath been the love with us, that boldness we may have in the day of the judgment, because even as He is, we — we also are in this world; 18fear is not in the love, but the perfect love doth cast out the fear, because the fear hath punishment, and he who is fearing hath not been made perfect in the love; 19we — we love him, because He — He first loved us; 20if 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? 21and this [is] the command we have from Him, that he who is loving God, may also love his brother.
