Job 19

25. For I know that my redeemer liveth, and that he shall stand at the latter day upon the earth:
26. And though after my skin worms destroy this body, yet in my flesh shall I see God:
27. Whom I shall see for myself, and mine eyes shall behold, and not another; though my reins be consumed within me.

Job is believed to be one of the oldest books in the Bible, here in his misery Job knows that he will see GOD with his own flesh, his redeemed body he receives at the resurrection. So even in the oldest books of Scripture the fathers of our faith knew of and believed in a future resurrection, one where they would see their redeemer.
