But thou, O Lord, shalt endure for ever,.... This address is made to Christ, as is clear from Ps 102:25, compared with Heb 1:10, who is a divine Person, endures for ever, is from everlasting to everlasting, unchangeably the same in his love, power, wisdom, faithfulness, &c.
and though he died as man, he will die no more; he is alive, and lives for evermore; and because he lives, his people shall live also; and he will come again to take them to himself: and, as Mediator, he is King for ever; always continues, as such, to rule over, protect, and defend his people; and is a Priest for ever, and ever lives to make intercession for them; and his blood, righteousness, and sacrifice, have a constant virtue in them, to take away sin, and secure from it: the consideration of the perpetuity of Christ, in his person and offices, was a comfort to the psalmist under his troubles, and in a view of his own declining state: the Targum is,"but thou, O Lord, thy habitation continues for ever in heaven:''and thy remembrance to all generations; the remembrance of his name Jehovah, or Jesus, or Immanuel, or any other, is sweet and precious to his saints in all ages; and so the remembrance of his works, of what he has done and suffered, especially the great work of redemption; for the remembrance of which the ordinance of the Lord's supper is appointed to be continued till his second coming; and his Gospel is an everlasting one, which will transmit the memory of him to men in every age, to the end of the world; and though all flesh is as grass, and every man dies, even the ministers of the word, yet that itself lives for ever.
