““perfect—Cain rose up and slew his brother Abel. For Abel’s sacrifice, an innocent lamb, had found favor with Jehovah. This, Noah said, showed that those who rebel against Jehovah always hate those who obey Him. Abel was also a prophet and warned his brother of his sinful path. Abel paid for his warning with his life. The event also showed a prophet’s fate. The way of Cain, a man of the world, warred against the way of the Spirit of Jehovah, against a man of the spirit.””
