Ultimate proof of God?

Proof weakens faith

Nothing is ultimately proved in this world of the seen primarily because it is based on change. There are a host of books written specifically to prove the existence of God. They say this in their titles. They say this even though it says in the Bible we can only please God through belief. Why does it say that? I would say it is because if we can prove God exists then there is no purpose or power in faith. 

The Power is in Belief

If you accept actual proof then you wipe out completely any need to believe. Firstly, we ultimately can not prove anything with certainty, we can only prove to our own personal satisfaction. Secondly, the single presence of constant change in the seen world precludes all proof accompanied by certainty. Proof then is merely a stumbling block to faith, which is the purpose of proof. It is stumbling block to our belief principally, one might say. by doubt brought into the personal picture by the devil. All thought, even in the physical sciences, depends on faith, on the personal power to believe.
