That as sin has reigned unto death, even so might grace reign through righteousness unto eternal life by Jesus Christ our Lord.
All Commentaries on Romans 5:21 Go To Romans 5
Tertullian of Carthage
AD 220
"reigned unto death, even so might grace reign through righteousness unto (eternal) life by Jesus Christ".
By a figure we die in our baptism, but in a reality we rise again in the flesh, even as Christ did, "that, as sin has reigned in death, so also grace might reign through righteousness unto life eternal, through Jesus Christ our Lord."
