What is heaven?

This morning I had my last Christian Belief class at church. There were around 15 of us fighting our heavy eyes and heads to stay focus to Wayne Grudem and our dear church elder. In fact, I shoved in two cups of coffee to my throat just to make sure I was sober during the class. We were learning about “What is heaven?” It was like a sum up of the entire 20 doctrines that we had during this program.
