What is the the ground of our justification? It is that, because of His complete obedience, Christ merits and receives a full reward: the salvation and sanctification of all His children. His obedience is both active and passive: both fulfilling the just requirements of the law and taking upon Himself the penalty and punishment of the law. In this two-fold way, He makes complete intercession for us, giving us access to God. Thus we say that we are justified solely by Christ's blood.
