Williams⁽ⁱ⁾ ¹¹ it is so because the message that you have heard from the beginning is this: We should love one another. ¹² We must not be like Cain who belonged to the evil one and butchered his brother. And why did he butcher him? Because his own actions were wicked and his brother's upright. ¹³ You must not be surprised, brothers, if the world hates you. ¹⁴ We know that we have passed out of death into life, because we love our brothers. Whoever does not continue to love continues still in death. ¹⁵ Anyone who keeps on hating his brother is a murderer; and you know that no murderer can have eternal life remaining in him.
