1 John 3:10-12

World English Bible

¹⁰ In this the children of God are revealed, and the children of the devil. Whoever doesn’t do righteousness is not of God, neither is he who doesn’t love his brother. ¹¹ For this is the message which you heard from the beginning, that we should love one another; ¹² unlike Cain, who was of the evil one, and killed his brother. Why did he kill him? Because his deeds were evil, and his brother’s righteous.
