It lets you sleep at night. It carries you over rough times. Eventually, it can see you right through the grave. Biblical hope is not a mere desire for something good to happen. It is A confident expectation and desire for something good in the future.
Biblical hope has moral certainty in it.
Now let us go to the Scripture to see where I get this understanding of Biblical hope. Though we speak thus, yet in your case, beloved, we feel sure of better things that belong to salvation. For God is not so unjust as to overlook your work and the love which you showed for his sake in serving the saints, as you still do. And we desire each one of you to show the same earnestness in realizing the full assurance of hope until the end, so that you may not be sluggish, but imitators of those who through faith and patience inherit the promises. The reason the writer is so sure that his readers will not be among the apostates is that they have not only been loving servants for God's sake in the past but are still serving.
