People like to have a direct experience and perception of things. The fact that we cannot see God at work, that He is not manifest in person before our eyes, seems to be a big sticking point. Show me God, and then I’ll believe in Him, the sceptics posit. However, even according to the management gurus of the 21st century, God would be a pretty average manager if He was frantically running around in front of us directing everything.
If you look at the top CEO’s in the modern business world, they setup a managerial hierarchy and then take a back seat, allowing things to function effortlessly without their direct day-to-day involvement. Instead, you’ll probably find them relaxing at the golf course with their friends. So the fact that we can’t see God creating and maintaining this universe may not be a disqualification, but rather credit to His expert management sense. He manages the material universes remotely, and instead spends quality time in the spiritual realm intimately relating with His devotees.
