Charles Ellicott Commentary Luke 20:36

"for neither can they die any more: for they are equal unto the angels; and are sons of God, being sons of the resurrection." — Luke 20:36 (ASV)

Neither can they die any more.—The record of this teaching is peculiar to Saint Luke. The implied thought is that death and marriage are correlative facts in God’s government of the world, with one filling the gaps caused by the other. In eternal life, there is no need for an addition to the number of the elect by this means, and therefore no provision is made for it.

Equal unto the angels.—The single Greek word that corresponds to these four English words is again peculiar to Saint Luke.

The children of God, being the children of the resurrection.—It is obvious that here the resurrection is assumed to be to life and to a share in the divine kingdom. The fact that men were counted worthy to obtain that resurrection was a proof that they were children of God, and as such on the same footing as those other sons of God, whom the language of Scripture (Job 1:6; Job 38:7, and possibly Genesis 6:12) identified with the angels.
