Malachi 3:6

For I am the Lord,....

A reproof of the Jews for their corrupting God's ordinances and sacrilegiously robbing him of his dues, with a charge to them to amend this matter, and a promise that, if they did, God would return in mercy to them,

I am the Lord, I change not - The new dispensation of grace and goodness, which is now about to be introduced, is not the effect of any change in my counsels; it is, on the contrary, the fulfillment of my everlasting purposes; as is also the throwing aside of the Mosaic ritual, which was only intended to introduce the great and glorious Gospel of my Son. And because of this ancient covenant, ye Jews are not totally consumed; but ye are now, and shall be still, preserved as a distinct people - monuments both of my justice and mercy.

Ro 11:29: compare the whole chapter, in which God's mercy in store for Israel is made wholly to flow from God's unchanging faithfulness to His own covenant of love. So here, as is implied by the phrase "sons of Jacob" (Ge 28:13;

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.

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. There is something exceedingly improving to the mind in a contemplation of the Divinity. It is a subject so vast, that all our thoughts are lost in its immensity; so deep, that our pride is drowned in its infinity. Other subjects we can compass and grapple with; in them we feel a kind of self-content, and go our way with the thought, “Behold I am wise.” But when we come to this master-science, finding that our plumb-line cannot sound its depth, and that our eagle eye cannot see its height, we turn away with the thought, that vain man would be wise, but he is like a wild ass’s colt; and with the solemn exclamation, “I am but of yesterday, and know nothing.” No subject of contemplation will tend more to humble the mind, than thoughts of God. We shall be obliged to feel— “Great God, how infinite art thou, What worthless worms are we!” But while the subject humbles the mind it also expands it. He who often thinks of God, will have a larger mind than the man who simply plods around this narrow globe. He may be a naturalist, boasting of his ability to dissect a beetle, anatomize a fly, or arrange insects and animals in classes with well nigh unutterable names; he may be a geologist, able to discourse of the megatherium and the plesiosaurus, and all kinds of extinct animals; he may imagine that his science, whatever it is, ennobles and enlarges his mind.

I am the Lord, I change not - , better, more concisely, “I, the Lord I change not - . The proper name of God, “He who Is,” involves His unchangeableness. For change implies imperfection; it changes to that which is either more perfect or less perfect: to somewhat which that being, who changes, is not or has not. But God has everything in Himself perfectly. “Thou Alone, O Lord, Art what Thou Art, and Thou Art Who Art. For what is one thing in the whole and another in parts, and wherein is anything subject to change, is not altogether what Is. And what beginneth from not being, and can be conceived, as not being, and only subsisteth through another thing, returns to not-being; and what hath a ‘has been,’ which now is not, and a ‘to be,’ which as yet is not, that is not, properly and absolutely. But Thou Art what Thou Art. For whatever Thou Art in any time or “way,” that Thou Art wholly and always; and Thou Art, Who Art properly and simply, because Thou hast neither ‘to have been’ or ‘to be about to be;’ but only to be present; and canst not be conceived, ever not to have been.” “There is only one simple Good, and, therefore, One Alone Unchangeable, which is God.” “Our” life is a “becoming” rather than a simple “being;” it is a continual losing of what we had, and gaining what we had not, for “in as far as any one is not what he was, and is what he was not, so far forth he dieth and ariseth;” dieth to what he was, ariseth to be something otherwise. “Increase evidences a beginning; decrease, death and destruction. And, therefore, Malachi says, ‘I am God, and I change not,’ ever retaining His own state of being; because what has no origin cannot be changed.” So the Psalmist says Psa 102:27, “As a vesture, Thou shalt change them and they shall be changed, but Thou art the Same, and Thy years shall not fail;” and Balaam, controlled by God Num 23:19.
