The theme of the book of Romans is found here in vv. 16-17; a righteousness based on faith and not works, available to all. It is the power of God In Salvation.
Every major doctrine of the Bibl
e can be found in Romans. But all those blessed truths would be meaningless to us apart from the impartation of the righteousness of God, his saving grace, through the work of Christ on the cross providing redemption to all who will believe.
