Luke 20:34-39
34 And Jesus said to them, "The sons of this age marry and are given in marriage, 35 but those who are considered worthy to attain to that age and the resurrection from the dead, neither marry, nor are given in marriage; 36 for neither can they die anymore, for they are like angels, and are sons of God, being sons of the resurrection. 37 "But that the dead are raised, even Moses showed, in the passage about the burning bush, where he calls the Lord the God of Abraham, and the God of Isaac, and the God of Jacob. 38 "Now He is not the God of the dead, but of the living; for all live to Him." NAS
"For they are like angels" refers to their immortality, not a physical or lack of a physical body.
