Exactly. That is what we Amils point out all the time. Revelation 20:6 talks about those who have part in the first resurrection, which you said yourself right here is Christ's bodily resurrection. So, how do you think someone has part in Christ's resurrection (the first resurrection)?
After all he said, this is all you can say in response? He did address the point, but you're not getting it. His point is that the redemption of our bodies doesn't occur until the second coming of Christ.
Just like what Paul taught in 1 Corinthians 15.
1 Cor 15:22 For as in Adam all die, so in Christ all will be made alive. 23 But each in turn: Christ, the firstfruits; then, when he comes, those who belong to him.
So, this establishes that Paul is talking about the resurrection of the dead in Christ occurring when Christ comes again. He goes on to explain what happens at that time and then after that talks about different types of bodies and that the future body we will have is a spiritual body. And then he said this:
1 Cor 15:50 I declare to you, brothers and sisters, that flesh and blood cannot inherit the kingdom of God, nor does the perishable inherit the imperishable. 51 Listen, I tell you a mystery: We will not all sleep, but we will all be changed— 52 in a flash, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, the dead will be raised imperishable, and we will be changed. 53 For the perishable must clothe itself with the imperishable, and the mortal with immortality. 54 When the perishable has been clothed with the imperishable, and the mortal with immortality, then the saying that is written will come true: “Death has been swallowed up in victory.
So, this passage is speaking of what will happen when Christ comes again at the last trumpet. It speaks of the dead in Christ being raised, just like it says in 1 Cor 15:22-23 which says that will happen when He comes again. And then they, along with those who are alive at the time, will all be changed and will then have imperishable (incorruptible) and immortal bodies, which will be spiritual bodies (1 Cor 15:44).
That redemption of our bodies is still something all of the dead in Christ are waiting for in heaven (their souls and spirits are in heaven while their bodies are still dead in the graves) and we who are alive now are waiting for that as well.
