11For this is the message which you have heard from the beginning, that we are to love one another; 12not as Cain, who was of the evil one and murdered his brother. And for what reason did he murder him? Because his own deeds were evil, but his brother’s were righteous.
13Do not be surprised, brothers and sisters, if the world hates you. 14We know that we have passed out of death into life, because we love the brothers and sisters. The one who does not love remains in death. 15Everyone who hates his brother or sister is a murderer, and you know that no murderer has eternal life remaining in him.
