As we know, (all axioms are self-evident and hard to prove) but all phenomena or theorems follow the basic assumptions of those axioms no matter what particular branch of science or math they apply to
If we push every truth (whatever the field) to the bottom, we will always find that there are something fundamental but beyond our abilities to prove. It is so obvious yet hard to prove.
Likewise, (God’s existence is the Greatest Axiom to me), I experience His existence in my daily life. I depend on His guidance all the time and I talk to Him through prayers and get messages from Him through reading Bible. Yet I can’t prove it to you about His existence although I would like to. Because we are so limited in our abilities, limited in time and space, we can’t comprehend things beyond 3 dimension world and beyond our life times. Who knows what kind of infinite dimension world God has been there all the time?
As Newton pointed out long ago that not even the small model of our solar system he made, could exist without somebody who had made it; how can such a big universe exists without a Creator? Just like a raccoon, in a film I saw, that accidentally ran into a man’s workshop and turned on switches as random as can be, had put the workshop on fire in minutes, how can our Globe moving in such a high speed not colliding into another stars? How can our Globe rotate in an exact angle (about 23 degree) to guarantee right temperatures for us to live? Can all these be coincidences? What is the probabilities of this being random happenings? Wouldn’t that be more reasonable to believe some Super Being, namely God, has created it for us?
Because that which is known about God is evident within us, for God made it evident to us; since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that we are without excuse.
Therefore regarding God as the Greatest Axiom, (His existence is self-evident and hard to prove) but for those who sincerely search for Him, He would be found, that is, God exists and He is willing to be found.
A. All Axioms are self evident and hard to prove
I. God’s existence is the Greatest Axiom
I. Therefore, God’s Existence is self-Evident and hard to prove.
