BSB(i)
11 This is the message you have heard from the beginning: We should love one another.
12 Do not be like Cain, who belonged to the evil one and murdered his brother. And why did Cain slay him? Because his own deeds were evil, while those of his brother were righteous.
13 So do not be surprised, brothers, if the world hates you.
14 We know that we have passed from death to life, because we love our brothers. The one who does not love remains in death.
15 Everyone who hates his brother is a murderer, and you know that eternal life does not reside in a murderer.
