1 John 3:10-12

21st Century King James Version

¹⁰ By this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither is he that loveth not his brother.

¹¹ For this is the message that ye heard from the beginning: that we should love one another.

¹² Be not as Cain, who was of that wicked one and slew his brother. And why did he slay him? Because his own works were evil, and his brother’s righteous.
