Justification
“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.”
Where does the Bible speak of Christ’s “Active Obedience”?
By the fact that Christ died on the Cross not for men but in obedience to God.
