Luke 20:37-38

But [as for the fact] that the dead are raised [from death], even Moses showed, in the passage about the burning bush, when he calls the Lord THE GOD OF ABRAHAM, THE GOD OF ISAAC, AND THE GOD OF JACOB. [Ex 3:6] Now He is not the God of the dead, but of the living [so these forefathers will be among the resurrected]; for all live [in a definite relationship] to Him.”
