I think this song is about the book of Revelation in the Bible. This is about the end time as prophesied by John the Apostle. Nearly all of the lyrics of the song are from the Bible, although many are taken out of context. Dave is a Christian and this is his take on the End Times. The Bible tells us that blessed are the dead who die in Christ. Jesus is the Firstborn of the Dead. The only way to Eternal Life is by being washed in the Blood of Jesus Christ. He is the Way, the Truth and the Life and no person comes to the Father but by Him. The Synagogue of Satan is unbelievers who pose as Christians. Jesus told us nations will rise against nation and we see that right now. The Bible tells us that believers names will be written in stone. Overall, a super song that speaks the truth of the One True God.
