RWB:
Davidai does not understand what thrones, sit upon them, and judgment was given to them all means is because he is thinking everything literally. That is the problem.
We, Christians, already experienced the First Resurrection (bring born again), and the judgment that was given to us is the WORD of GOD, not our own! When we preach the Word of God, we are bringing judgment as a fire that will burn the people and are also as cool waters for the thirsty soul to be saved. See, when we are raised up in Christ, we become His Judges on Earth, bringing the Word of God to the masses. This is how we "seat" - - we rule with Christ by preaching His Gospel. Wr are the ambassadors that represents His Kingdom on Earth. If you or any Christians who have physically died before the Second Coming, our souls will immediately go to heaven and continue reign with Christ. We were always spiritually alive in Christ on Earth after being born again. But for the "rest of the dead" - those who have not yet being saved (born again), their souls remain dead. When their flesh dies, their souls will remain in the grave in silence, not having any conscience, until they will be resurrect when Christ returns on the last day in the future. THAT will be the second resurrection for them. We already have the first resurrection. We do not need to worry about the second resurrection because our souls inside us, whether we are physically alive or not, are already made alive. If we physically dies before Christ returns, our souls will simply transfer to heaven - immediately! In fact, it won't be consider as the resurrection since we already had the first resurrection when we heard the gospel, repent and believe in Christ. When we do, we are given judgment and sit as kings and priest in His Kingdom. Right now.
David entirely lacks understanding of Amil doctrine but has convinced himself that he is the one who will expose Amil error. His inquisitive, perhaps arrogant mind lacks spiritual discernment. He is one of those the Bible tells us is ever learning and never coming to knowledge of truth.
