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.
All Commentaries on Romans 5:15 Go To Romans 5
Augustine of Hippo
AD 430
The gift excels in two ways: first, because grace abounds much more in that it bestows eternal life even though death reigns in the temporal sphere because of the death of Adam, and second, because by the condemnation of one sin the death of many came about through Adam, whereas by the forgiveness of many sins through our Lord Jesus Christ grace has been given for eternal life.
