4:7 If thou doest well, shalt thou not be {e} accepted? and if thou doest not well, sin lieth at the {f} door. And unto thee [shall be] his {g} desire, and thou shalt rule over him.
(e) Both you and your sacrifice shall be acceptable to me.
(f) Sin will still torment your conscience.
(g) The dignity of the first born is given to Cain over Abel.
4:7 If thou dost well, shalt thou not be accepted? - Either,
1. If thou hadst done well, as thy brother did, thou shouldest have been accepted as he was. God is no respecter of persons; so that if we come short of acceptance with him, the fault is wholly our own. This will justify God in the destruction of sinners, and will aggravate their ruin. There is not a damned sinner in hell, but if he had done well, as he might have done, had been a glorified saint in heaven. Every mouth will shortly be stopt with this. Or,
2. If now thou do well: if thou repent of thy sin, reform thy heart and life, and bring thy sacrifice in a better manner; thou shalt yet be accepted. See how early the gospel was preached, and the benefit of it here offered even to one of the chief of sinners. He sets before him death and a curse; but, if not well - Seeing thou didst not do well, not offer in faith, and in a right manner, sin lieth at the door - That is, sin only hinders thy acceptance. All this considered, Cain had no reason to he angry with his brother, but at himself only. Unto thee shall be his desire - He shall continue in respect to thee as an elder brother, and thou, as the first - born, shall rule over him as much as ever. God's acceptance of Abel's offering did not transfer the birth - right to him, (which Cain was jealous of) nor put upon him that dignity, and power, which is said to belong to it, Gen 49:3.
4:1-7 When Cain was born, Eve said, I have gotten a man from the Lord. Perhaps she thought that this was the promised seed. If so, she was wofully disappointed. Abel signifies vanity: when she thought she had the promised seed in Cain, whose name signifies possession, she was so taken up with him that another son was as vanity to her. Observe, each son had a calling. It is the will of God for every one to have something to do in this world. Parents ought to bring up their children to work. Give them a Bible and a calling, said good Mr. Dod, and God be with them. We may believe that God commanded Adam, after the fall, to shed the blood of innocent animals, and after their death to burn part or the whole of their bodies by fire. Thus that punishment which sinners deserve, even the death of the body, and the wrath of God, of which fire is a well-known emblem, and also the sufferings of Christ, were prefigured. Observe that the religious worship of God is no new invention. It was from the beginning; it is the good old way, Jer 6:16. The offerings of Cain and Abel were different. Cain showed a proud, unbelieving heart. Therefore he and his offering were rejected. Abel came as a sinner, and according to God's appointment, by his sacrifice expressing humility, sincerity, and believing obedience. Thus, seeking the benefit of the new covenant of mercy, through the promised Seed, his sacrifice had a token that God accepted it. Abel offered in faith, and Cain did not, Heb 11:4. In all ages there have been two sorts of worshippers, such as Cain and Abel; namely, proud, hardened despisers of the gospel method of salvation, who attempt to please God in ways of their own devising; and humble believers, who draw near to him in the way he has revealed. Cain indulged malignant anger against Abel. He harboured an evil spirit of discontent and rebellion against God. God notices all our sinful passions and discontents. There is not an angry, envious, or fretful look, that escapes his observing eye. The Lord reasoned with this rebellious man; if he came in the right way, he should be accepted. Some understand this as an intimation of mercy. If thou doest not well, sin, that is, the sin-offering, lies at the door, and thou mayest take the benefit of it. The same word signifies sin, and a sacrifice for sin. Though thou hast not done well, yet do not despair; the remedy is at hand. Christ, the great sin-offering, is said to stand at the door, Re 3:20. And those well deserve to perish in their sins, that will not go to the door to ask for the benefit of this sin-offering. God's acceptance of Abel's offering did not change the birthright, and make it his; why then should Cain be so angry? Sinful heats and disquiets vanish before a strict and fair inquiry into the cause.
