Hebrews 11:1 Now faith is the substance of things hoped for, the evidence of things not seen.
People have in days past asked me to prove there is this God I worship. I tell them that I cannot and that I will not prove anything concerning God.
However, you can discover proof for yourselves independent of anything I might say or do. In many ways it is a scientific experiment. A substance is quantitative. Evidence is qualitative.
In order to receive and examine the result of this scientific experiment, one needs to use the elements that are called out that are directly related to the subject matter under testing.
The only two matters listed in Hebrews 11:1 are faith and hope. This faith and hope have to be related to the subject under examination, God.
Romans 10:17 So then faith cometh by hearing, and hearing by the word of God.
In order to obtain faith to test faith, one must obtain it from the Word of God. This is not faith as the world knows it. It must be faith from God.
Romans 12:3d God hath dealt to every man the measure of faith.
Everyone has a measure of faith. Do you recognize the faith that is to be examined? Can you hear it? Do you read the Word of God? If not, how do you expect to discover and test this faith from God? You cannot prove God without it.
Isaiah 32:1.3-4 Behold, a king shall reign in righteousness, and princes shall rule in judgment. And the eyes of them that see shall not be dim, and the ears of them that hear shall hearken. The heart also of the rash shall understand knowledge, and the tongue of the stammerers shall be ready to speak plainly.
Those who are subjects of the King will have eyes to see and ears to hear. Notice that the heart of the rash will understand. You will gain an understanding heart.
