And be found in him, not having my own righteousness, which is of the law, but that which is through the faith of Christ…
This righteousness is the only ground of acceptance with God. It is not of mine, but of God, as in His grace He has provided it, so that it is said of us we are "justified freely by His grace." It is wrought out by Christ and in His blood (Romans 5:9); or it is "through the redemption that is in Christ Jesus." It becomes ours through faith. This faith is "counted for righteousness," or subjectively "with the heart man believeth unto righteousness." Of the possessor of such righteousness it may be said that "a man is justified in the sight of God." Christ obeyed the law for us and suffered its penalty, and the merit of this obedience unto death becomes ours as soon as we can say, "We have believed in Jesus." He that was unrighteous becomes righteous, and escapes the condemnation which sin merits (Romans 8:1; Romans 1:18); nay, enjoys the benefit of redemption (Ephesians 1:7). When works of law are disclaimed, and faith is simply reposed on God, guilt is cancelled, acceptance enjoyed, and such a change of state involves a change of character (Romans 8:4). The sinner is not indeed held by any legal fiction to be innocent. The entire process implies his guilt, but he is no longer exposed to its penalty; he is held, or dealt with, as a righteous person, "the external justice of Christ Jesus being imputed to Him" (Hooker). And the result is (Romans 8:30). This righteousness, Divine in its origin, awful in its medium, and fraught with such results, was the essential element of Paul's religion and the distinctive tenets of His theology.
