It’s difficult for humans to believe in something they can’t see. Something inside each of us wants tangible proof before we believe. Things the human mind considers to be “real” are those things we perceive with our natural senses, which is why it’s a challenge for most of us to function in the spiritual realm. We’re asked to believe in Someone we can’t see, listen to a voice we can’t hear, and depend on a power that’s invisible. And that’s a challenge some find too difficult, and most of them handle the problem in one of two ways. Either they deny the spiritual world exists altogether, or they go to the other extreme and focus their worship on physical objects. The first group ignores the spiritual, the second turns it into something they can see and touch.
