John Gill Commentary Luke 20:35

"but they that are accounted worthy to attain to that world, and the resurrection from the dead, neither marry, nor are given in marriage:" — Luke 20:35 (ASV)

But those who shall be accounted worthy to obtain that world The world to come, eternal life and happiness; not by their own works and merits, but through the blood, sacrifice, and righteousness of the Messiah; and the resurrection from the dead; that is, the first resurrection, the resurrection unto life, which only the dead in Christ will enjoy; otherwise all will be raised: but some to the resurrection of damnation: these neither marry, nor are given in marriage; there will be no need of any such practice, for the reasons that follow.
