God does not need to let me know. But if god wants me to know or expects things from me then it would be the best thing to just let me know and then give me the knowledge I would have gotten on the journey to "find" him.Why does God need to let you know? Would not you become wiser figuring it all out on your own? Look how much more knowledge and wisdom you would acquire along the journey to Discover anything. Further, how many really listen when they are told? On the other hand, people don't question that which they Discovered for themselves. Example: What freezes quicker cold water or hot water? I could tell you, however how many would never believe until they Discover the answer for themselves?
In this way he could make sure the communication is 100% correct. In your way there will be many that won't get this knowledge. Is that what god desires?
