But instead of acknowledging his sin, Cain continued to complain of the injustice of God and to cherish jealousy and hatred of Abel. He angrily reproached his brother, and attempted to draw him into controversy concerning God’s dealings with them. In meekness, yet fearlessly and firmly, Abel defended the justice and goodness of God. He pointed out Cain’s error, and tried to convince him that the wrong was in himself. He pointed to the compassion of God in sparing the life of their parents when He might have punished them with instant death, and urged that God loved them, or He would not have given His Son, innocent and holy, to suffer the penalty which they had incurred. All this caused Cain’s anger to burn the hotter. Reason and conscience told him that Abel was in the right; but he was enraged that one who had been wont to heed his counsel should now presume to disagree with him, and that he could gain no sympathy in his rebellion. In the fury of his passion he slew his brother.
Cain hated and killed his brother, not for any wrong that Abel had done, but “because his own works were evil, and his brother’s righteous.”1 John 3:12. So in all ages the wicked have hated those who were better than themselves. Abel’s life of obedience and unswerving faith was to Cain a perpetual reproof. “Everyone that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved.”John 3:20. The brighter the heavenly light that is reflected from the character of God’s faithful servants, the more clearly the sins of the ungodly are revealed, and the more determined will be their efforts to destroy those who disturb their peace.
