29If ye know that he is righteous, ye know that every one also that doeth righteousness is begotten of him.

3 Behold what manner of love the Father hath bestowed upon us, that we should be called children of God; and such we are. For this cause the world knoweth us not, because it knew him not. 2Beloved, now are we children of God, and it is not yet made manifest what we shall be. We know that, if he shall be manifested, we shall be like him; for we shall see him even as he is. 3And every one that hath this hope set on him purifieth himself, even as he is pure. 4Every one that doeth sin doeth also lawlessness; and sin is lawlessness. 5And ye know that he was manifested to take away sins; and in him is no sin. 6Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither knoweth him. 7My little children, let no man lead you astray: he that doeth righteousness is righteous, even as he is righteous: 8he that doeth sin is of the devil; for the devil sinneth from the beginning. To this end was the Son of God manifested, that he might destroy the works of the devil. 9Whosoever is begotten of God doeth no sin, because his seed abideth in him: and he cannot sin, because he is begotten of God. 10In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother. 11For this is the message which ye heard from the beginning, that we should love one another: 12not as Cain was of the evil one, and slew his brother. And wherefore slew he him? Because his works were evil, and his brother’s righteous.

13Marvel not, brethren, if the world hateth you. 14We know that we have passed out of death into life, because we love the brethren. He that loveth not abideth in death. 15Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him. 16Hereby know we love, because he laid down his life for us: and we ought to lay down our lives for the brethren. 17But whoso hath the world’s goods, and beholdeth his brother in need, and shutteth up his compassion from him, how doth the love of God abide in him? 18My little children, let us not love in word, neither with the tongue; but in deed and truth.
