11For this is the message which you have heard from the beginning, that we should love one another;12not as Cain, who was of the evil one and slew his brother. And for what reason did he slay him? Because his deeds were evil, and his brother’s were righteous.
13Do not be surprised, brethren, if the world hates you.14We know that we have passed out of death into life, because we love the brethren. He who does not love abides in death.15Everyone who hates his brother is a murderer; and you know that no murderer has eternal life abiding in him.16We know love by this, that He laid down His life for us; and we ought to lay down our lives for the brethren.
