So also is the free gift not like the offense. For if through the offense of one many are dead, much more the grace of God, and the gift by grace, which is by one man, Jesus Christ, has abounded unto many.

Diodorus of Tarsus

At first sight it may seem that this verse contradicts what Paul said [in verse ] above, for there he spoke of death having come to all humanity, whereas here he says only that many have died. In fact there is no contradiction, because death, although it came upon all because we have all sinned, came only to test and to try everyone. Death does not destroy all sinners automatically but only those who persist in their sins. By saying that “many died” Paul shows merely that many turned out to be unrepentant in their sins. .
