Well, trying to prove something on faith alone already complicates things. Trying to get someone else to understand it with a different upbringing and beliefs is nigh impossible. But those still confused about what to believe might be open to suggestions.

Religion is essentially how one was raised by their parents. The growing exception to this which is seen as individuals further and further themselves from traditional values occurs during adolescence. It could be just in rebellion of the parents' beliefs, another attempt at independence, or just thinking differently of the world compared to their predecessors, but individuals are more and more looking for new religions to define their lives and explain the paranoia that occurs every now and then. I could go on and on about those confused souls that claim their religion is not having a religion for example (which is essentially a paradox), but that would go beyond the scope of the statement you posed Spector. In retrospect, trying to convince others of your religion that have stuck to the values implanted into them at childhood is pointless. But when asked your opinion about religion if ever, passing on what you were taught or have learned in your experiences might set them on the right track. Because religion, if looked at clearly, is the only real reason we're still sane in this world (the other method which analysts usually take is to explain everything through reason quintessentially as religion explains things usually through some sort of hierarch governing the world).
