12 Like a cloak You will fold them up, And they will be changed. But You are the same, And Your years will not fail.”
Verse 12 continues the quote from Psalm 102:25-27. This verse continues the argument about the temporality of the universe.
12 Like a cloak You will fold them up,
Both the universe and angels are temporary and subject to decay.
And they will be changed.
God will completely change the created order one day (2 Pe 3:11-13). The Messiah will exchange the decaying garment of creation that grows old and worn out for a new one. The heavens and earth will be transformed in the Millennium. After the 1000-year reign, Messiah will then introduce the eternal state. The immutable Son, however, never changes.
But You are the same, And Your years will not fail.”
Both the quote from Psalms 45:6-7 and the quote here focus on the eternality of the Son. The Messiah never changes or grows old. He is immutable. Neither will His kingdom wear out. This is a reference to the eternal state (2 Pe 3:10-13). He Himself is immutable (He 13:8). Angels are mutable or changeable.
The only lasting stability in the universe is in an unchanging God.
The Son, the eternal Creator of the universe, stands in contrast to created beings such as angels. The Son is eternal and will reign eternally.
The universe as it now stands is perishable—it wears out like a garment—however, the Son’s kingdom is eternal. As Creator, the Son existed before creation and will exist after it; He will give creation stability. Creation is not permanent, but the Son is eternal. The created order grows old and is perishable. Christ the Messiah’s kingdom will remain the same even after God shakes creation itself (He 12:26-28).
The eternal Son of God is the One through whom all things were created and are sustained. No angel could be compared to Him. The Son had no beginning, nor will He have an end. He is the Creator, Almighty, unchangeable and eternal.
