1 John 3:10
King James Version
“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.”
Context
7Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous.
8He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.
9Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born 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 that ye heard from the beginning, that we should love one another.
12Not as Cain, was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother’s righteous.
13Marvel not, my brethren, if the world hate you.
