Inheriting Adam's Sin

Therefore, just as through one man sin entered into the world, (Romans 5:12a)

"Therefore" connects what follows with what has just been declared, namely, that as believers we have been reconciled to God by the sacrifice of His Son Jesus Christ (vv. 8–11). Now Paul begins the analogy of Christ with Adam, the common principle being that, in each case, a far-reaching effect on countless others was generated "through one man."

In the case of Adam, it was through one man that sin entered into the world. It is important to note that Paul does not say that sin originated with Adam but only that sin in the world, that is, in the human realm, began with Adam. Sin originated with Satan, who “has sinned from the beginning” (1 John 3:8). John does not specify when that beginning was, but it obviously was before the creation of Adam and Eve, because they were tempted by Satan. . . .
