When Jesus Returns What New Knowledge Will We Acquire?

What I think is interesting is that when Jesus returns, slowly He will show us things we could never have figured out before. Maybe during the 1000 year reign or afterward in the New City He will explain to us how He could always have existed outside of space and time, or He might just say we were not created to be able to understand that. Maybe God could never create a being who could do that, for only God could ever fully understand Himself on some points.
