Repentance is one of the most powerful redemptive principles of the restored gospel of Jesus Christ. Without it, there would be no eternal progression, no possibility of becoming Christlike, no relief from the burden of guilt that every human incurs in a lifetime. With it, there is the glorious promise uttered by Isaiah that even for grievous sins there might be forgiveness: "Though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool" (Isa. 1:18).
