Lift up your eyes to the heavens, and look upon the earth beneath: for the heavens shall vanish away like smoke, and the earth shall grow old like a garment, and they that dwell in it shall die in like manner: but my salvation shall be forever, and my righteousness shall not be abolished.
All Commentaries on Isaiah 51:6 Go To Isaiah 51
Irenaeus of Lyons
AD 202
[Some malignantly assert] that if heaven is indeed the throne of God and earth his footstool, and if … the heaven and earth shall pass away, then when these pass away, the God who sits above must also pass away, and therefore he cannot be the God who is over all. In the first place, they are ignorant what the expression means, that heaven is [his] throne and the earth [his] footstool. For they do not know what God is, but they imagine that he sits after the fashion of a person and is contained within the bounds, but nothing contains God. And they are also unacquainted with [the meaning of] the passing away of the heaven and earth; but Paul was not ignorant of it when he declared, “For the form of this world passes away.” In the next place, David explains their question, for he says that when the fashion of this world passes away, not only shall God remain, but his servants also, expressing himself thus in Psalm 101: “In the beginning, you, O Lord, have founded the earth, and the heavens are the works of your hands. They shall perish, but you shall endure, and all shall grow old as a garment; and as a piece of clothing you shall change them, and they shall be changed. But you are the same, and your years shall not fail. The children of your servants shall continue, and their seed shall be established forever”; pointing out plainly what things they are that pass away and who it is that does endure forever—God, together with his servants.
