5:12 {10} Wherefore, as by {l} one man {m} sin entered into the world, and death by sin; and so death passed upon all men, {n} for that all have sinned:
(10) From Adam, in whom all have sinned, both guiltiness and death (which is the punishment of the guiltiness) came upon all.
(l) By Adam, who is compared with Christ, and similar to him in this, that both of them make those who are theirs partakers of that which they have: but they are not the same in this, that Adam derives sin into them that are his, even into their very nature, and that to death: but Christ makes them that are his partakers of his righteousness by grace, and that to life.
(m) By sin is meant that disease which is ours by inheritance, and men commonly call it original sin: for so he calls that sin in the singular number, whereas if he speaks of the fruits of it, he uses the plural number, calling them sins.
(n) That is, in Adam.
5:12 Wherefore. The section which now follows is one of the most difficult in the Bible to explain clearly in the compass of a few words. It opens up one of the profoundest questions of theology. The wherefore refers to the reconciliation (atonement) of Christ spoken of in Ro 5:11. Christ's work of atonement and the effect of Adam's sins are contrasted.
As by one man. By the sin of Adam.
Sin entered into the world. The world of mankind is meant.
Death by sin. Death was led in by sin. Had there been no sin, there had been no death. The tree of life stood in the midst of the garden (Ge 2:9).
So death passed upon all men. As the result of one man's sin.
For that all have sinned. The personal sins of responsible persons are not now spoken of, but all the race sinned in Adam, its representative, infants, idiots, and all. Hence all die.
5:12 Therefore - This refers to all the preceding discourse; from which the apostle infers what follows. He does not therefore properly make a digression, but returns to speak again of sin and of righteousness. As by one man - Adam; who is mentioned, and not Eve, as being the representative of mankind. Sin entered into the world - Actual sin, and its consequence, a sinful nature. And death - With all its attendants. It entered into the world when it entered into being; for till then it did not exist. By sin - Therefore it could not enter before sin. Even so - Namely, by one man. In that - So the word is used also, 2Cor 5:4. All sinned - In Adam. These words assign the reason why death came upon all men; infants themselves not excepted, in that all sinned.
5:12-14 The design of what follows is plain. It is to exalt our views respecting the blessings Christ has procured for us, by comparing them with the evil which followed upon the fall of our first father; and by showing that these blessings not only extend to the removal of these evils, but far beyond. Adam sinning, his nature became guilty and corrupted, and so came to his children. Thus in him all have sinned. And death is by sin; for death is the wages of sin. Then entered all that misery which is the due desert of sin; temporal, spiritual, eternal death. If Adam had not sinned, he had not died; but a sentence of death was passed, as upon a criminal; it passed through all men, as an infectious disease that none escape. In proof of our union with Adam, and our part in his first transgression, observe, that sin prevailed in the world, for many ages before the giving of the law by Moses. And death reigned in that long time, not only over adults who wilfully sinned, but also over multitudes of infants, which shows that they had fallen in Adam under condemnation, and that the sin of Adam extended to all his posterity. He was a figure or type of Him that was to come as Surety of a new covenant, for all who are related to Him.
