This is the righteousness through which grace reigns unto eternal life. It is important to note just here the condition of this divine righteousness. Since it is a blessing bestowed by God and coming from God, it cannot be based upon works. It would then not be grace, but debt. This is so because works would be an inappropriate means.
Works point to man.
This would imply human righteousness, not divine righteousness. The condition, then, must look to Christ. It must mean reliance upon what Christ did for man. It must signify trust in the blood of Christ. Human righteousness, evidently, is for the righteous only.
