Now faith is the substance of things hoped for, the evidence of things not seen. (Hebrews 11:1)
The Greek word for "substance" is hupostasis. It is a scientific term, the opposite of hypothesis or theory. It is that which rests upon facts. In chemistry it would be the chemical which settles at the bottom of the test tube after you have made an experiment. Dr. A. T. Robertson translates substance as "title deed." What is the title deed?

Therefore faith rests upon the Word of God. Our dogmatism comes from the Book....

Evidence is something you take into court to prove your case.
Faith is not a leap in the dark. Faith is not a "hope so." Faith is substance and evidence - substance for a scientific mind, and evidence for a legal mind. If you really want to believe, you can believe....
