Things are hidden temporarily only as a means to revelation. For there is nothing hidden except to be revealed, nor is anything kept secret except in order that it may be made known. If any man has ears to hear, let him hear. Mark 4:22,23.
One thing about us humans which is very "natural" and yet of very real concern is our propensity to give our attention and our time to humans instead of, or as a substitute for, Jesus Christ Himself. This is an age-old temptation for us. We just naturally prefer to listen to and worship someone we can see here and now rather than "hearing" and "seeing" the Unseen Invisible One for ourselves.
