So we are “not like Cain,” who showed that he “originated with the wicked one” by ‘slaughtering his brother’ in a violent manner characteristic of the manslayer Satan. (Genesis 4:2-10; John 8:44) Cain slaughtered Abel “because his own works were wicked, but those of his brother were righteous.”

13. If we hate our brother, why should we make this a matter of prayer?

¹³ Really, “everyone who hates his brother is a manslayer.” Physical murder may not be committed (as when Cain killed Abel out of envy and hatred), but the hater would prefer that his spiritual brother not be alive.
