God is so big that there is not enough books in the world for the intellectually thinking to believe in Him. To know about Him and knowing Him is as simple as this. The knowledgeable must become as knowing nothing before Him. Because if anyone thinks that they are knowledgeable it’s because they don’t know the way that they should. Knowing God is being able to hear and understand his voice.
Hebrews 11:6New King James Version
The common denominator of every religion is having a relationship with God. Even as you understand Him doesn’t make Him the real and living God unless you can hear Him in your own living and loving relationships. It is then that we understand what it is to have Faith in you possession. God is as big as your faith that pleases Him. There is plenty more where that came from.
6 But without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him.
