1 John 3
10 Ref 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 Ref For this is the message which you heard from the beginning, that we should love one another;
12 Ref unlike Cain, who was of the evil one, and killed his brother. Why did he kill him? Because his works were evil, and his brother's righteous.
13 Ref Don't be surprised, my brothers, if the world hates you.
14 Ref We know that we have passed out of death into life, because we love the brothers. He who doesn't love his brother remains in death.
