The blood of atonement, so appropriated as to prompt to unceasing testimony, is the infallible weapon of victory. So long as Satan could point to the broken law, he could say, "Your case is hopeless, there is no pardon, no mercy in law; it is a straightedge to lay on your character and show its crookedness. It cannot make you straight. It must condemn you. So all your attempts to be righteous are vain. You would do wisely to throw off all allegiance to that hard Master who reaps where he has not sown, whose law is impracticable, and whose commandments are grievous." But the death of Christ puts a new hope into the despairing soul. It brings to an end the reign of law. so far as it is the ground of pardon. The blood of Christ lays a practicable basis for the forgiveness of sins. Thus the devil and his hostile powers are deprived of their strength, which rested on the law as the sole ground of justification.
