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.
