What you and I believe is very similar, at least up to a point. We both believe that after death, we live on as spirits. However, this transition from physical body to spirit, that's where we differ.
You describe it as "the spirit leaves the body". I describe it as "the physical body is replaced with a spiritual body".
If you read 1 Corinthians 15 you should see that will not happen until the last trumpet when Jesus returns. It does not happen immediately upon death. That is not stated anywhere.
The problem with "the spirit leaves the body": It requires you to answer a complicated question, which I don't think you can answer. And the question is: What are you? Are you a body? If yes, then you would have to agree with "the physical body is replaced with a spiritual body" otherwise you would have to claim that you do not live on after death, and I don't think you are claiming that. If you say you are spirit, living inside of a body, then when the body dies, you don't die, because you are not the thing that died. Only your vessel died, because you are the spirit, not the body. If you say you are the combination of spirit and body, then you have a real problem because it would not allow the spirit and body to separate from each other, as both parts would have their own consciousness and that would require you to be two people. So that doesn't work. Any way you slice it, your consciousness determines what you are, because where your consciousness is, there you are.
You are not making any sense here. You are the one who somehow thinks that we can't exist and be conscious without a body, but that is simply not the case and not taught anywhere in scripture. You're trying to come up with convoluted ways to support your doctrine, but it doesn't work. Scripture portrays physically/bodily dead people as still being conscious. Explain how Jesus was talking to Moses and Elijah at His transfiguration if they supposedly knew nothing as you believe about those who are physically dead (or who were physically dead in OT times...your beliefs are hard to follow).
The reason why the body replacement theory makes sense: It allows us to understand what has changed since Jesus' resurrection. Something must have changed, otherwise what was the point of Jesus' death and resurrection? And when we look at OT scriptures, we can clearly see what has changed, and that is that in the OT the saints did not go to heaven upon death. Nowhere does it say that any saint went to heaven when they died, or that they went on to live as spirits when they died.
They went to what is called Abraham's bosom (Luke 16:19-31) and were conscious there just as the rich man in that passage was conscious in hell or Hades.
Instead, we see countless examples of the dead resting in the dust, with their fathers. These examples can not be denied.
That's just their bodies. Why do you continue to not differentiate between the body, soul and spirit? There's no reason for you to do that.
And when we accept the statement that "the dead know nothing", we can confirm that the dead, in those days, lost consciousness.
But that contradicts the fact that Moses and Elijah were conscious despite being physically/bodily dead. Jesus spoke to them. So, you don't know what you're talking about. You're ignoring examples of physically/bodily dead people being conscious because you have decided that the dead knowing nothing can only mean one thing. But, you failed to look at the context of that verse as I showed you (which you ignored).
Their bodies were not replaced with spiritual bodies.
No one's body has been replaced with a spiritual body except for Jesus so far. You are way off base on this.
The physical body was all they had, and so when they died, they actually died, just like God said "to dust you will return".
Where are you getting the idea that their physical body was all they had? You're just making things up here.
Today, it's different. Today, when you die, you get a new body instantly so you never have to experience the state of death, because Jesus gave us eternal life, but the old testament saints did actually experience the state of death because the new spiritual body was not yet available to them.
Where is this taught? Stop making claims without backing them up with scripture.
My doctrine fits perfectly with scripture.
Not even close.
Yes, it does. You are lacking in discernment on this and need to ask God for wisdom about it (James 1:5-7). Why don't you try to tell Moses and Elijah that they knew nothing when they were dead whenever you see them. They will both get a good laugh out of that.
You have to pretend that all those OT verses don't really mean what they say. I don't have that problem. I can accept what they say, and make sense of it all.
They do mean what they say, but you don't understand what they mean. This type of argument is weak and pointless. This is what premils do when they say that us Amils don't let certain scriptures mean what they say. We have to discern what they mean. There's a scripture that says there is a beast with seven head and ten horns. Does that mean it's a literal beast with seven literal heads and ten literal horns? Of course not.
