1 John 3:14 WEB

¹²  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  Don't be surprised, my brothers, if the world hates you.

¹⁴  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.

¹⁵  Whoever hates his brother is a murderer, and you know that no murderer has eternal life remaining in him.

¹⁶  By this we know love, because he laid down his life for us. And we ought to lay down our lives for the brothers.
