Since you say your paper is due in a few hours, I suggest you refer to the famous words on faith by Paul in Hebrews 11 in the Old Testament. It begins with the following verse.
Now faith is the substance of things hoped for, the evidence of things not seen.
If you don't have a Bible handy, you can get the whole chapter from Google. Paul offers numerous examples of religious faith throughout history up to his time. There is also an essay on faith in a publication called The Rambler, which you can access on Google.
I am only offering these suggestions because you have so little time.
