Psalms 102:25

25Thou hast aforetime founded the earth Here the sacred writer amplifies what he had previously stated, declaring, that compared with God the whole world is a form which quickly vanishes away; and yet a little after he represents the Church as exempted from this the common lot of all sublunary things, because she has for her foundation the word of God, while her safety is secured by the same word. Two subjects are therefore here brought under our consideration. The first is, that since the heavens themselves are in the sight of God almost as evanescent as smoke, the frailty of the whole human race is such as may well excite his compassion; and the second is, that although there is no stability in the heavens and the earth, yet the Church shall continue steadfast for ever, because she is upheld by the eternal truth of God. By the first of these positions, true believers are taught to consider with all humility, when they come into the divine presence, how frail and transitory their condition is, that they may bring nothing with them but their own emptiness. Such self-abasement is the first step to our obtaining favor in the sight of God, even as He also affirms that he is moved by the sight of our miseries to be merciful to us. The comparison taken from the heavens is a very happy illustration; for how long have they continued to exist, when contrasted with the brief span of human life, which passes or rather flies away so swiftly? How many generations of men have passed away since the creation, while the heavens still continue as they were amidst this continual fluctuation? Again, so beautiful is their arrangement, and so excellent their frame-work, that the whole fabric proclaims itself to be the product of God’s hands (161) And yet neither the long period during which the heavens have existed, nor their fair embellishment, will exempt them from perishing. What then shall become of us poor mortals, who die when we are as yet scarcely born? for there is no part of our life which does not rapidly hasten to death.

Interpreters, however, do not all explain these words, The heavens shall perish, in the same way. Some understand them as expressing simply the change they shall undergo, which will be a species of destruction; for although they are not to be reduced to nothing, yet this change of their nature, as it may be termed, will destroy what is mortal and corruptible in them, so that they shall become, in a manner, different and new heavens. Others explain the words conditionally, and make the supplement, “If it so please God,” regarding it as a thing absurd to say that the heavens are subject to corruption. But first, there is no necessity for introducing these supplementary words, which obscure the sense instead of making it plainer. In the next place, these expositors improperly attribute an immortal state to the heavens, of which Paul declares that they “groan and travail in pain,” like the earth and the other creatures, until the day of redemption, (Romans 8:22) because they are subject to corruption; not indeed willingly, or in their own nature, but because man, by precipitating himself headlong into destruction, has drawn the whole world into a participation of the same ruin. Two things are to be here attended to; first, that the heavens are actually subject to corruption in consequence of the fall of man; and, secondly, that they shall be so renewed as to warrant the prophet to say that they shall perish; for this renovation will be so complete that they shall not be the same but other heavens. The amount is, that to whatever quarter we turn our eyes, we will see everywhere nothing but ground for despair till we come to God. What is there in us but rottenness and corruption? and what else are we but a mirror of death? Again, what are the changes which the whole world undergoes but a kind of presage, yea a prelude of destruction? If the whole frame-work of the world is hastening to its end, what will become of the human race? If all nations are doomed to perish, what stability will there be in men individually considered? We ought therefore to seek stability no where else but in God.
