Old Testament encourages hope of eternal life?

Rom 15.4 says, “For everything that was written in former times was written for our instruction, so that through endurance and through encouragement of the scriptures we may have hope” (NET)

Our hope is centered in eternal life, Tt 1.3; 3.7. It is the hope of justification before God (being accepted by him), Gal 5.5. The NT does not carry over the promises of physical blessings (aside from necessities, Mt 6.33), contrary to proponents of the theology of prosperity.

Eternal life was not prominent in the OT. So how can it help us maintain our hope? Your comments will be most appreciated.
