Verse 27. But thou art the same, or, "thou art he." As a man remains the same when he has changed his clothing, so is the Lord evermore the unchanging One, though his works in creation may be changed, and the operations of his providence may vary. When heaven and earth shall flee away from the dread presence of the great Judge, he will be unaltered by the terrible confusion, and the world in conflagration will effect no change in him; even so, the Psalmist remembered that when Israel was vanquished, her capital destroyed, and her temple levelled with the ground, her God remained the same self- existent, all-sufficient being, and would restore his people, even as he will restore the heavens and the earth, bestowing at the same time a new glory never known before. The doctrine of the immutability of God should be more considered than it is, for the neglect of it tinges the theology of many religious teachers, and makes them utter many things of which they would have seen the absurdity long ago if they had remembered the divine declaration, "I am God, I change not, therefore ye sons of Jacob are not consumed."
And thy years shall have no end. God lives on, no decay can happen to him, or destruction overtake him. What a joy is this! We may lose our dearest earthly friends, but not our heavenly Friend. Men's days are often suddenly cut short, and at the longest they are but few, but the years of the right hand of the Most High cannot be counted, for they have neither first nor last, beginning nor end. O my soul, rejoice thou in the Lord always, since he is always the same.
EXPLANATORY NOTES AND QUAINT SAYINGS
Verse 27. Thou art the same. The essence of God, with all the perfections of his nature, are pronounced the same, without any variation from eternity to eternity. So that the text doth not only assert the eternal duration of God, but his immutability in that duration; his eternity is signified in that expression, "thou shalt endure;" his immutability in this, "thou art the same." To endure, argues indeed this immutability as well as eternity; for what endures is not changed, and what is changed doth not endure. "But thou art the same," awx xta, doth more fully signify it. He could not be the same if he could be changed into any other thing than what he is. The Psalmist therefore puts, not thou hast been or shall be, but thou art the same, without any alteration; thou art the same, that is, the same God, the same in essence and nature, the same in will and purpose, thou dost change all other things as thou pleaseth; but thou art immutable in every respect, and receivest no shadow of change, thought never so light and small. The Psalmist here alludes to the name Jehovah, I am, and doth not only ascribe immutability to God, but exclude everything else from partaking in that perfection. Stephen Charnock.
