1 John 3:2-12

2 Beloved, 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.
3 And every one that hath this hope [set] on him purifieth himself, even as he is pure.
4 Every one that doeth sin doeth also lawlessness; and sin is lawlessness.
5 And ye know that he was manifested to take away sins; and in him is no sin.
6 Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither knoweth him.
7 [My] little children, let no man lead you astray: he that doeth righteousness is righteous, even as he is righteous:
8 he 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.
9 Whosoever is begotten of God doeth no sin, because his seed abideth in him: and he cannot sin, because he is begotten of God.
10 In 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.
11 For this is the message which ye heard from the beginning, that we should love one another:
12 not 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.
