New Defender's Study Bible Notes
5:12 by one man. There is no warrant in the New Testament for the heretical notion that “Adam” is simply a generic term representing the human race. He was “one man,” in fact “the first man” (I Corinthians 15:45). There were no pre-Adamite men, as some have alleged, and certainly no population of evolving hominids becoming Adam. In fact, Christ Himself made it clear that Adam and Eve were “from the beginning of the creation” (Mark 10:6, quoting Genesis 1:27). Adam was a real person, directly created and made by God, and so was Eve. The entire argument of Romans 5:12-21 becomes irrelevant if the Genesis record of the creation and fall of Adam did not happen just as recorded in Genesis 1–3, and this would mean there is no reality in the saving work of Christ either. Destroying or distorting the plain Genesis record undermines and eventually destroys the gospel of salvation. Such a devastating undermining of the Christian faith is surely not warranted by the fragmentary and self-contradictory fossil evidences that have been alleged to support the notion of human evolution.
5:12 death by sin. Thus there was no death before sin entered the world. The finished creation was “very good” (Genesis 1:31), with an abundance of food and all other provisions for man and the animals. There was certainly no struggle for existence, or survival of the fittest, for every creature was created fit for its own environment. When Adam sinned, God brought the curse of decay and death not only upon Adam but also upon all His dominion (Genesis 3:17-19). See also I Corinthians 15:21-22; Romans 8:20-22.
5:14 Adam to Moses. Thus Adam is as real a person as Moses, and only the most extreme skeptics would dare to question the historical reality of Moses.
5:14 had not sinned. The only creatures in history who have not sinned like Adam (note Romans 5:12) are the animals. But death reigns over these also, because of Adam’s sin. In fact, the very ground was cursed, out of which all living bodies had been made, when their God-appointed steward sinned.
5:14 figure. The first Adam is thus a contrasting type of “the last Adam” (I Corinthians 15:45), the one bringing death into the world, the other bringing eternal life to the world. This typological theme is beautifully developed in Romans 5:15-21, but all this would be pointless if Adam were not uniquely the first man, and the father of all other men. In fact, God promised redemption through “Him that was to come” at the same time He pronounced the curse on Adam and his dominion (Genesis 3:15).
