"For you have need of endurance, so that after you have done the will of God, you may receive the promise:

“For yet a little while,
And He who is coming will come and will not tarry.
Now the just shall live by faith;
But if anyone draws back,
My soul has no pleasure in him.”

But we are not of those who draw back to perdition, but of those who believe to the saving of the soul."
- Hebrews 10:36-39

"Now faith is the substance of things hoped for, the evidence of things not seen. For by it the elders obtained a good testimony.

By faith we understand that the worlds were framed by the word of God, so that the things which are seen were not made of things which are visible." - Hebrews 11:1-3
