5 Trust in the Lord with all thine heart; and lean not unto thine own understanding.
6 In all thy ways acknowledge him, and he shall direct thy paths.
No matter what the "facts" are, we have to trust and believe that mans certainty, or what man believes to be insurmountable is not a hinderance for God.
If we believe each and everything that we see and we walk in the natural, intellectualizing everything, how can we have faith?
11 Now faith is the substance of things hoped for, the evidence of things not seen.
God's word is clear. In order to hope for anything we must believe that God will supply our need when we cannot see a solution.
We must walk by faith and not by sight.
