Charles H. Spurgeon on Psalms 89:30

If his children forsake my law. An objection is supposed: `Suppose this seed who are included in the covenant fall into transgression, how shall the covenant stand fast then?' The covenant, with the seed, shall stand for ever, but the seed must be a holy seed. Then the objector supposes —`Suppose the seed become unholy?' Well, God explains —"If his children forsake my law, and walk not in my judgments" —that is, if the seed practically fall away —"If they break my statutes, and keep not my commandments; then will I visit their transgression with the rod, and their iniquity with stripes. Nevertheless my lovingkindness will I not take from him, nor suffer my faithfulness to fail." Mark the case. What is it that God will do? The case supposed is that the seed of Christ forsakes the law and breaks his statutes. I need not say to you that that is realized every day. These are not the ungodly or the unconverted that are spoken of, but God's own children. Do you say, `Can they be guilty of breaking God's statutes, and forsaking God's law?' We do it every day. There is no single day of our lives that we do not do it. . . .

How astonished many would be, if they knew what the real case was of those perhaps whom they admire, and think highly advanced and exalted in the Divine life, if they were to know the falls, the wretched falls, falls in heart, in word and in practice; if they were to know the deep distress that the children of God, who are far advanced as they suppose in the Divine life, are continually suffering from the effect of such transgression! That is exactly what God says; he comes and contemplates such a case, and he says, "If they break my statutes, and keep not my commandments, then" —what? What will God do? Some people say, "Then God will leave them." Those who object to the doctrine of final perseverance say this: "It is true he will preserve the believer from the toils of the Devil and the temptations of the world, but not from the breaking forth of his own natural evil." He may be betrayed by that, and finally lost. God exactly meets that case; he contemplates the worst case —actual transgression. He says, "If a child of mine breaks my law". He does not say anything about the Devil, or the outward temptations of the world; but he says, "If they forsake my law and break my statutes." Let us be instructed by God. He does not say he will leave them and forsake them. Mark what he will do! He say —"I will visit their transgressions with the rod, and their iniquity with stripes." That is the provision which God has made in his covenant: and it is delightful to see how God has contemplated our case to the uttermost. There is nothing in our history that God has not met in the covenant with Christ. If you are in union with Christ, and a partaker of the covenant, your case is met in every conceivable emergency. Nothing can befall you which is not contemplated —nothing which God has not provided for. Even if you fall, God has provided for it; but take heed; the provision involves much that will be terrible and desperately painful to your mind. There is nothing to encourage sin about it; there is nothing to give us license, nothing to lead a man to boast, "I am safe at last." Be it so: but safe how? How will God secure their safety? "I will visit their transgression with the rod, and their iniquity with stripes." —Capel Molyneux.
