John Gill: Christ's active and passive obedience secure eternal life and an escape from the wrath to come

The complete justification of God's people, is brought about by the death of Christ: justification is sometimes ascribed to the obedience of Christ; by the obedience of one shall many be made righteous (Rom. 5:19), and sometimes to the blood of Christ, being now justified by his blood, verse 9. And both are concerned in justification: the one is what is commonly called his active obedience; the other his passive obedience; and both together, with the holiness of his nature; are imputed for justification: his righteousness entitles to life; and his blood, his sufferings, and death, secure from wrath to come; and; therefore, it may well be said, with a view to Christ's dying for his people, who is he that condemneth?
