Albert Barnes Commentary Revelation 22:3

"And there shall be no curse any more: and the throne of God and of the Lamb shall be therein: and his servants shall serve him;" — Revelation 22:3 (ASV)

And there shall be no more curse. This is undoubtedly designed to be in strong contrast with our present dwelling. It is affirmed that what is now properly called a curse, or whatever is part of the curse pronounced on man by the fall, will be unknown there.

The earth will no longer be cursed and will produce no more thorns and thistles. Man will no longer be compelled to earn his bread by the sweat of his brow. Woman will no longer be doomed to bear the sufferings she endures now. And the dwellings of the blessed will no longer be cursed by sickness, sorrow, tears, and death.

But the throne of God and of the Lamb shall be in it. God will reign there forever; the principles of purity and love which the Lamb of God came to establish will pervade that blessed dwelling for all eternity.

And his servants shall serve him. All His servants who are there—that is, all the inhabitants of that blessed world. For the meaning of this passage, see Barnes on Revelation 7:15.
