Equal unto the angels - Who neither marry nor die. See the Jewish testimonies to the resurrection of the human body quoted at length on 1 Corinthians 15:42 (note).

Neither can they die any more,.... Therefore there will be no need of marrying to procreate children, to keep up a succession of men, any more than there is among the angels:

for they are equal unto the angels; in spirituality, purity and immortality; See Gill on Matthew 22:30.

and are the children of God: as they are now by adopting grace; but, as yet, it does not appear as it will then, what they are and will be:

being the children of the resurrection; as Christ was declared to be the son of God by his resurrection, so will they appear to be the children of God by their resurrection to eternal life; for though others will rise, yet not to everlasting life, and thus appearing to be children of God, they will also be heirs of God, and enjoy the inheritance, which they will always live to possess in their persons; and therefore the case being different with them from the children of the world, they will not marry, nor be given in marriage, as they are.

Equal unto the angels (ἰσάγγελοι)

Only here in New Testament.

Neither can they die any more: for they are equal unto the angels; and are the children of God, being the {h} children of the resurrection.

(h) That is, men who partake in the resurrection: for as we truly say that they will indeed live who will enjoy everlasting bliss, so do those indeed rise who rise to life; though if this word resurrection is taken generally, it refers also to the wicked, who will rise to condemnation, which is not properly life, but death.

20:27-40 Then came to him certain of the Sadducees. For notes on the Sadducees silenced, see Mt 22:23-33. Compare Mr 12:18-27.

children of God-not in respect of character but nature; "being the children of the resurrection" to an undecaying existence (Ro 8:21, 23). And thus the children of their Father's immortality (1Ti 6:16).

20:27-38 It is common for those who design to undermine any truth of God, to load it with difficulties. But we wrong ourselves, and wrong the truth of Christ, when we form our notions of the world of spirits by this world of sense. There are more worlds than one; a present visible world, and a future unseen world; and let every one compare this world and that world, and give the preference in his thoughts and cares to that which deserves them.
