Luke 20:36-38

36In fact, they can no longer die, because they are like the angels. And since they are sons of the resurrection, they are sons of God.

37Even Moses demonstrates that the dead are raised, in the passage about the burning bush. For he calls the Lord ‘the God of Abraham, the God of Isaac, and the God of Jacob.’1 38He is not the God of the dead, but of the living, for to Him all are alive.”
