Luke 20:37
Now that the dead are raised, even Moses shewed at the bush, when he calleth the Lord the God of Abraham, and the God of Isaac, and the God of Jacob. Now that the dead are raised, even Moses shewed at the bush, when he calleth the Lord the God of Abraham, and the God of Isaac, and the God of Jacob.
At the bush God called Himself the God of Abraham, and the God of Isaac, and the God of Jacob, and that declaration proves that the dead are raised. He regards His promised work as certain and its outcome as already accomplished. The dead saints will hear the voice of the Son of God, come out of their graves, and rise to immortal life. His enduring relationship with the patriarchs means they will live again, and the risen saints will belong to Him as His people in a close and tender relationship, so the dead live to Him. Denying the resurrection conflicts with the Scriptures.
