REASON: Can We Prove God’s Existence?

How do we even know of the existence of a Being who is beyond all our experience and all our reasoning powers?

We are supposed to believe in God. But two basic questions then arise: what do we mean by the notion of a God?, and, how can we know such a being even exists? What is this concept of the divine? anyway? Can we prove the existence of a God? Can we prove that Jesus Christ is this God? What is the limit to human language and reasoning about these things? Does faith even need proof? With reason or proof, how do we avoid self-deception?
