Consider Charles Haddon Spurgeon’s first message in the volumes he delivered. It is based on Malachi 3:6, “I am the Lord, I change not; therefore ye sons of Jacob are not consumed.” The title was “The Immutability of God.” Here are some selected quotes…
It has been said by some one that “the proper study of mankind is man.” I will not oppose the idea, but I believe it is equally true that the proper study of God’s elect is God; the proper study of a Christian is the Godhead. The highest science, the loftiest speculation, the mightiest philosophy, which can ever engage the attention of a child of God, is the name, the nature, the person, the work, the doings, and the existence of the great God whom he calls his Father…
Would you lose your sorrows? Would you drown your cares? Then go, plunge yourself in the Godhead’s deepest sea; be lost in his immensity; and you shall come forth as from a couch of rest, refreshed and invigorated. I know nothing which can so comfort the soul; so calm the swelling billows of grief and sorrow; so speak peace to the winds of trial, as a devout musing upon the subject of the Godhead.
You have been shaken on the rock, not the rock under you. I have heard that a gentleman said to a (black man), “I can’t think how it is you are always so happy in the Lord and I am often downcast.” “Why Master,” said he, “I throw myself flat down on the promise—there I lie; you stand on the promise—you have a little to do with it, and down you go when the wind comes, and then you cry, ‘Oh! I am down;’ whereas I go flat on the promise at once, and that is why I fear no fall.”
Down I go on the promise flat! no standing up for me. That is where you should go—prostrate on the promise; and remember, every promise is a rock, an unchanging thing. Therefore, at his feet cast yourself, and rest there forever.
Jacob was a man of prayer—a man who wrestled, and groaned, and prayed. Sons of God cannot live without prayer. They are wrestling Jacobs. They are men in whom the Holy Ghost so works, they they can no more live without prayer than I can live without breathing. They must pray. Sirs, mark you, if you are living without prayer, you are living without Christ; and dying like that, your portion will be in the lake which burneth with fire. God redeem you, God rescue you from such a lot!
There is little to love in (us) after (we) are born, that if he had not loved (us) before then, he would have seen no reason to choose (us) after; but since he loved (us) without works, he loves (us) without works still; since their good works did not win his affection, bad works cannot sever that affection; since (our) righteousness did not bind his love to (us), so (our) wickedness cannot snap the golden links. He loved (us) out of pure sovereign grace, and he will love (us) still. But we should have been consumed by the devil, and by our enemies—consumed by the world, consumed by our sins, by our trials, and in a hundred other ways, if God had ever changed.
