Charles Spurgeon the the Immutability of God's Threatening

Every threatening of God, as well as every promise shall be fulfilled. Talk of decrees! I will tell you of a decree: “He that believeth not shall be damned.” That is a decree, and a statute that can never change. Be as good as you please, be as moral as you can, be as honest as you will, walk as uprightly as you may,—there stands the unchangeable threatening: “He that believeth not shall be damned.” What sayest thou to that, moralist? Oh, thou wishest thou couldst alter it, and say, “He that does not live a holy life shall be damned.” That will be true; but it does not say so. It says, “He that believeth not.” Here is the stone of stumbling, and the rock of offence; but you cannot alter it. You must believe or be damned, saith the Bible; and mark, that threat of God is an unchangeable as God himself. And when a thousand years of hell’s torments shall have passed away, you shall look on high, and see written in burning letters of fire, “He that believeth not shall be damned.” “But, Lord, I am damned.” Nevertheless it says ”shall be“ still. And when a million ages have rolled away, and you are exhausted by your pains and agonies, you shall turn up your eye and still read “SHALL BE DAMNED,” unchanged, unaltered. And when you shall have thought that eternity must have spun out its last thread—that every particle of that which we call eternity, must have run out, you shall still see it written up there, “SHALL BE DAMNED.” O terrific thought! How dare I utter it? But I must. Ye must be warned, sirs, “lest ye also come into this place of torment.” Ye must be told rough things; for if God’s gospel is not a rough thing & the law is a rough thing; Mount Sinai is a rough thing. Woe unto the watchman that warns not the ungodly! God is unchanging in his threatenings. Beware, O sinner, for “it is a fearful thing to fall into the hands of the living God.”
