What’s interesting is that when Jesus (who is God) was on earth, He wasn’t granted full access to all of the Father’s knowledge. Like for instance, when Jesus said that the time of His second coming was known only to the Father, not to Jesus. And if the Father didn’t reveal all, even to His own Son, how silly for us to think He’d reveal deep mysteries to us. Even in eternity, I have to believe that there’s plenty of information of interest to us that God will choose to keep to Himself.
