Cain is declared by the Spirit of God in the apostle to have been "of that wicked one." The first thing we see in him is his religion. He renders to God, as offering or sacrifice, the fruit of the cursed ground, the produce of his own toil. But this was unbelief. It was the denial of all that had happened since the creation, the _religious_ denial of it. It was the direct contradiction of the way of faith, or of Abel. Abel took the way of the promise to God, the bloody victory of the woman’s Seed, the death and resurrection of Christ, and offered of his flock; but Cain refused to see man’s ruin and God’s redemption, giving God the fruit of the earth; in effect saying, that He was to be read and known in the thorns and the thistles, the sweat, and the sorrow, and the death; and by the solemn services of his altar he was denying all truth. This was the way of a heart deeply departed from God. He was laying the scene of ruin at God’s door, as Adam, ere he repented, had laid down the sin itself there. His next way is in terrible keeping with all this. He hates his brother, being of that wicked one who is a murderer (John viii. 44), and in process of time he slays him. Tremendous fruit of the apostate, departed nature. He was the first of that generation who delivered Jesus to be crucified--self-righteous and murderous. For envy the Jews delivered Jesus; and Cain slew Abel because his own works were evil and his brother’s righteous. It is the world. "Marvel not, my brethren, if the world hate you. We know that we have passed from death unto life, because we love the brethren. He that loveth not his brother abideth in death. Whosoever hateth his brother is a murderer, and ye know that no murderer hath eternal life abiding in him." The Lord pleaded with him. See iv. 6, 7. His heart had conceived the sin, but his hand had not brought forth fruit unto death; and with a voice of long-suffering grace and warning the Lord pleaded with him. The grace was despised; this grace of pleading with him at the last hour, as the grace of the promise had been despised before. "This is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil." The light which the Lord Jesus was bringing with Him was the light of life or salvation. Isa. xlix. 6; John viii. 12. And _this_ was the light which Cain hated and refused. There is the light of righteousness or holiness. But the refusal of it is not without remedy. In that light the Lord God had come into the garden and called, "Adam, where art thou?" Adam could not stand it; for he had sinned. It was intolerable to him. He had come short of that glory. He retreats from it. And then the Lord God shines in another light. The promise is made. The character of the glory is changed. God seats Himself in a light which the sinner can approach, and, believing, Adam comes forth.
