1 John 3:10-14

10By this it is evident who are the children of God, and who are the children of the devil: whoever does not practice righteousness is not of God, nor is the one who does not love his brother.

11For this is the message that you have heard from the beginning, that we should love one another.

12We should not be like Cain, who was of the evil one and murdered his brother. And why did he murder him? Because his own deeds were evil and his brother's righteous.

13Do not be surprised, brothers, that the world hates you.

14We know that we have passed out of death into life, because we love the brothers. Whoever does not love abides in death.
