Now faith is the substance of things hoped for, the evidence of things not seen. Hebrews 11:1

“Abraham in hope believed and so became the father of many nations, just as he had been told. For in this hope we were saved, for the hope that is seen is no hope at all. Therefore we do not hope for what we can already see, we do not fix our eyes on what is seen, but on what is unseen. For what is seen is temporary, but what is unseen is eternal. So, let us walk by faith, not by sight, and if we hope for what we do not yet see, we should wait for it patiently.”
