Should people need to prove God exists? If you ask this question, you also must ask what kind of proof would be sufficient and to whom it should be proven. When you talk about proof, you are talking about establishing some degree of certainty about the existence of God. That is where faith comes in. Faith is the assurance, confirmation, and the title deed of the things we hope for. It is the proof of things we do not see, the conviction of their reality, and it perceives as real fact what is not revealed to the senses (Hebrews 11). It takes greater faith to believe that an unseen God exists than it does to just dismiss Him because you cannot physically confirm that He is there.
