It will do you no good if you choose a faith based on popularity or status. The Divine will not connect to you if you can't learn how to hear Its voice. There are those who require proof before they will believe in the Divine Spirit. They want to see how your version stands up to their already preconceived notion of what the Divine entails. We have all met folks who ask for proof of our deities, only to offer little proof of their own.
Proof of existence is one of the most tenuous threads in the business of divinity.
One man's truth is another man's myth. We only accept the 'facts' that stand up to our personal set of rules. Proof from sources outside our belief can be easily dismissed, countered by our own faith. Faith is accepting the notion that there exist things and conditions outside our capacity to understand. Requiring proof in Spirit is like asking a blind man to describe the color blue.
