The Bible speaks a lot of hope: the Blessed Hope, the hope of salvation, the hope of that which is to come, and so much more. Job, Psalms and the Proverbs have so much hope. Cling to that hope: hope that better and more complete times are yet to come.

The Bible (Hebrew 11:1) says

Now faith is the substance of things hoped for, the evidence of things not seen.

Paraphrased, that's "Reaching out and grasping that which is not there, and holding on until it becomes reality."
