Why don’t you write more about what we’ll be doing in the intermediate state in your Heaven book?

The reason I don’t address activities about the intermediate state is because there are not a lot of details given to it. We do know there will be conversations, musical instruments, gatherings, worship, etc. If someone understands the greatness of God they realize he’s the source of all knowledge and all adventure. Therefore to be immediately in his presence, and see him for who he is, is the very opposite of boring. This is just as true in the intermediate state as on the New Earth. Even though those in the intermediate state are awaiting resurrection they are still in the presence of God.
