Biblical faith, not blind faith

Biblical Christian faith, is not without evidence or proof.

Now faith is the assurance of things hoped for, the conviction of things not seen. - Hebrews 11:1 (ESV)

That word for conviction, in Greek, can properly be translated as proof.

As Christians, we have proof and assurance of the things we hope for that have not been seen.

Blind faith is for the atheist or agnostic. 

Our faith is more like believing that air or gravity exists, without seeing it. Not believing the universe came out of nothingness, which logically, leaves you with nothing.
