The WT idea of judgment goes something like this: You are being judged right now by how active you are in the book and magazine placing work and also others are being judged based on their response to your magazines. Armageddon isn't so much a judgment as it is a reward for publishers. You get all the cool houses and stuff of the non-JWs.
What I was astounded to learn after leaving the WT was that there is no general judgment described in the Bible. In fact, there are at least three judgments.
First, there is the judgment of church age believers at the judgment seat of Christ (1 Cor. 3:11-15). This is a judgment of those who have trusted Christ and built their lives upon that solid foundation. Their ministries for Christ will be examined to see if they will be rewarded or not. Regardless of whether they win or lose rewards, they will be saved. “ If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire ” (1 Cor. 3:15).
Second, there is the judgment of the nations following the Great Tribulation. This is described in Matthew 25. These are not New Testament believers from the Church age. That group have by this time already been raptured away and received immortality and glorified bodies like Jesus has. These are perhaps billions of general folks who happen to survive the rise and fall of the Anti-Christ and his global wars and now stand in their mortal bodies at the very dawn of Christ's reign from Jerusalem here on earth. Jesus will sort these folks out.
Third, there is the judgment at the Great White Throne for the unsaved at the end of the Millennium. This is described in Revelation 20:11-15. These are judged by their works according to God’s holy law and condemned and cast into the lake of fire.
