Rebecca Writes

For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God. (2 Corinthians 5:21)

Those whom God effectually calls He also freely justifies, not by infusing righteousness into them, but by pardoning their sins, and by accounting and accepting them as righteous, not for anything wrought in them, or done by them, but for Christ’s sake alone. They are not justified because God reckons as their righteousness either their faith, their believing, or any other act of evangelical obedience. They are justified wholly and solely because God imputes to them Christ’s righteousness. He imputes to them Christ’s active obedience to the whole law and His passive obedience in death. They receive Christ’s righteousness by faith, and rest on Him. They do not possess or produce this faith themselves, it is the gift of God.

Christ, by His obedience and death, fully discharged the debt of all those who are justified, and by the sacrifice of himself through the blood of His cross, underwent instead of them the penalty due to them, so making a proper, real, and full satisfaction to God’s justice on their behalf. Yet because He was given by the Father for them, and because His obedience and satisfaction was accepted instead of theirs (and both freely, not because of anything in them), therefore they are justified entirely and solely by free grace, so that both the exact justice and the rich grace of God might be glorified in the justification of sinners.

He showed how long-suffering He is. He bore with us, and in pity He took our sins upon Himself and gave His own Son as a ransom for us – the Holy for the wicked, the Sinless for sinners, the Just for the unjust, the Incorrupt for the corrupt, the Immortal for the mortal. For was there, indeed, anything except His righteousness that could have availed to cover our sins? In whom could we, in our lawlessness and ungodliness, have been made holy, but in the Son of God alone? O sweet exchange! O unsearchable working! O benefits unhoped for! – that the wickedness of multitudes should thus be hidden in the One holy, and the holiness of One should sanctify the countless wicked!
