God Knows Absolutely Everything!
Daniel 2:22 (KJV)
He revealeth the deep and secret things: he knoweth what is in the darkness, and the light dwelleth with him.
Hebrews 4:13 (KJV)
Neither is there any creature that is not manifest in his sight: but all things are naked and opened unto the eyes of him with whom we have to do.
God is the first and the last. He Knows the beginning from the end, and the inbetweens!
