2 Corinthians 5:7

For in hope we were saved, but hope that is seen is not hope, for who hopes for what he already sees?

For now we see in a mirror dimly, but then face to face. Now I know in part, but then I will know fully just as I also have been fully known.

while we look not at the things which are seen, but at the things which are not seen; for the things which are seen are temporal, but the things which are not seen are eternal.

Now faith is the assurance of things hoped for, the conviction of things not seen.
