To them it was revealed, that not to themselves, but to you, did they minister these things, which now have been announced to you through those who preached the Gospel to you by the Holy Spirit sent out from heaven; which things angels desire to look into.
Now let's put it this way. Does God know everything? We believe that He does. "Known unto Him are all things," James said, "from the beginning" ( Acts 15:18 ). If God knows all things, then God can't learn anything. It's impossible for Him to learn anything because He already knows it. If God is ever going to know anything, then He already knows it.
