1. CAIN AND ABEL.
Abel’s sacrifice was not a sin-offering. Neither Cain nor Abel came before God with the conscience oppressed by a known transgression. It is the state of each of them that is in view, the state of man before God: the one owning himself driven justly out from His presence because of evil, yet drawing near to Him according to His grace; the other, the natural man insensible to sin. In God's answer to Cain (Gen. 4:7), the subject is positive transgression; and this confirms the thought that in the passage an offering for sin is meant, and not sin itself simply.
2. THE UTTERANCES OF THE CROSS.
The cross of Christ said, Man will not have God, even when He comes in grace. But it said also, God in infinite grace spared not His own Son, in order to reconcile man to Himself (2 Cor. 5:17-19).
3. DYING THOU SHALT DIE.
WHAT a horrible thing, if Adam had been able to eat of the tree of life, and to fill the world with immortal sinners, having no more fear of death than of God! But He allowed it not.
