For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord. – Romans 6:23
It may however be hence inferred with certainty, that our salvation is altogether through the grace and mere beneficence of God. He might indeed have used other words — that the wages of righteousness is eternal life; and then the two clauses would correspond: but he knew that it is through God’s gift we obtain it, and not through our own merits; and that it is not one or a single gift; for being clothed with the righteousness of the Son, we are reconciled to God, and we are by the power of the Spirit renewed unto holiness. And he adds, in Christ Jesus, and for this reason, that he might call us away from every conceit respecting our own worthiness.
