But that doesn't mean we can just disobey God and Jesus; we have to obey to the best of our ability as the saints we are. And also, it does not mean everything happens at once.
The non-saints do not go to hell, as hell does not exist. They do in fact go to the Lake of Fire, which is not hell. The Lake of Fire phrase is just a way of saying that these "non-saints" (for want of a better term) just go through a purification/refining/reconciliation process before they enter into the eternal-kingdom, a.k.a: Kingdom of heaven, or Kingdom of God. I believe that this refining and reconciliation process will occur during the Millennium and it will be the saints that will help Jesus carry out these roles and processes.
Then when everyone is reconciled with God, we all go into "heaven" which will be a new heavens and a new earth.
