That as sin had reigned — so grace also might reign — Which could not reign before the fall; before man had sinned. Through righteousness to eternal life by Jesus Christ our Lord — Here is pointed out the source of all our blessings, the rich and free grace of God. The meritorious cause; not any works of righteousness of man, but the alone merits of our Lord Jesus Christ. The effect or end of all; not only pardon, but life; divine life, leading to glory.
