All we like sheep have gone astray; we have turned every one to his own way; and the LORD hath laid on Him the iniquity of us all. Isaiah 53:6

Sin is an attack upon the moral government of God; it undermines the foundations of society, and were it permitted to have its way it would reduce everything to anarchy, and even destroy the governing power and the Ruler Himself…If sin were left unpunished it would soon be known through myriads of worlds, and in fact by ten thousand times ten thousand races of creatures, that they might sin with impunity; if one race had done so, why not all the rest? This would be a proclamation of universal license to rebel. 

The blotting out of sin seems hard till we see the cross, and then it appears easy enough. I have looked at sin till it seemed to blind me with its horror, and I said in myself, “This damned spot can never be washed out…0 sin, thou deep, eternal evil, what can remove thee?” And then I have seen the Son of God dying on the cross, and read the anguish of His soul, and heard the cries which showed the torment of His spirit when God His Father had forsaken Him, and it has seemed to me as if the blotting out of sin were the easiest thing under heaven. When I have seen Jesus die, I have not been able to understand how any sin could be difficult to remove. Let a man stand on Calvary and look on Him whom he hath pierced, and believe and accept the atonement made, and it becomes the simplest thing possible that his debt should be discharged now that it is paid, that his freedom should be given now that the ransom is found, and that he should be no longer under condemnation, since the guilt that condemned him has been carried away by his great Substitute and Lord. It is then because of what Jesus Christ has suffered in our stead that God for Christ’s sake hath forgiven us. ~ C.H. Spurgeon
