Who Against Hope Believed In Hope

What do we do when there appears to be no hope in our situation.

Abraham's testimony was Who against hope believed in hope.

Rom 4:16-24

16 Therefore it is of faith, that it might be by grace; to the end the promise might be sure to all the seed; not to that only which is of the law, but to that also which is of the faith of Abraham; who is the father of us all,

17 (As it is written, I have made thee a father of many nations,) before him whom he believed, even God, who quickeneth the dead, and calleth those things which be not as though they were.
