There have been many interesting statements made with regard to this subject, and I wish I could address them all. However, to do so in a single post would make it too long. So I'll address just two of them for now.
Also, Jesus said to the theif on the cross: "today you will be me in paradise".
No. That is not what he said. Let's examine His words carefully from Luke 23:43
He said ONE of the following:
1. And he said to him, "Truly I tell you today, you will be with me in Paradise."
2. And he said to him, "Truly I tell you, today you will be with me in Paradise."
Which one did He say? We cannot determine which from the Greek text, as there were no commas in the Greek that Luke wrote. For that matter there were no periods either, and no spaces between words. And all words were written in capitals.
I've heard some people say that it couldn't have been #1, because people don't talk that way. They say that in that case "today" is redundant. Of course He's telling them today ---- when else could He tell them?
But I think the expression was idiomatic. Indeed we still say something similar in our age. We say, "I'm telling you right now." We use "right now" for emphasis, even though strictly speaking it's unnecessary.
But what about 2 Corinthians 5:8?
We are of good courage, and we would rather be absent from the body and present with the Lord.
Isn't this a clear indication that we will be present with the Lord as soon as we die?
The real meaning becomes clear when we examine the context. Let's consider verses 1, 2, and 3 from this same chapter:
For we know that if the earthly tent we live in is destroyed, we have a building from God, a house not made with hands, eternal in the heavens. Here indeed we groan, and long to put on our heavenly dwelling, so that by putting it on we may not be found naked.
What is this "building from God"? This "house not made with hands"? This "heavenly dwelling" which we will put on? Is it not the resurrection body? Paul says that we "long to put it one so that we will not be found naked." If we were "found naked" would this mean we were in a "disembodied state"? But when we shall be raised to life, we will not be disembodied.
Paul said in I Cor 15, the great resurrection chapter in verse 44:
It is sown a physical body, it is raised a spiritual body.
Isn't our "spiritual body" of I Cor 15 identical to our "heavenly dwelling"
of II Cor 5?
So Paul's topic in II Cor 5 is the
resurrection! Paul wrote of this topic frequently in his letters. He showed that the resurrection is of paramount importance.
And now let me paraphrase the clause from II Cor 5:8 by adding a few words which make it clear that Paul had not ceased talking about the resurrection.
"We would rather be absent from this present mortal body, and present with the Lord in the immortal resurrection body."
Paul's analogy of the resurrection with the grain of wheat planted in the ground is a good one. The grain "dies" in the ground, and springs up in a very different form. It doesn't spring up immediately, but does so eventually. Likewise, we are not raised immediately after we die, but must await our resurrection.
Paul believed that our whole purpose is linked to our personal resurrection. In verse 32 of I Cor 15:
If the dead are not raised, "Let us eat and drink, for tomorrow we die."
Is he not saying that if there is no resurrection, then we may as well live happily, in the little time that we have, and never mind eternal matters, for there is no after-life?
Why would he think like that if we simply went to heaven at death? Surley we could live our lives as disciples of Christ, and receive our eternal reward(s) even though we had no resurrection of the body!
Some posts have referred to "soul sleep". I do not subscribe to that view.
I go much further. I think that when we die, we no longer exist! We
depend on the Lord to raise us up.
Our Lord and the apostles frequently referred to death as "sleep". Sometimes we have a dreamless sleep. We go to sleep, and the next thing we know, we have awakened with no memory of what happened while we were asleep. Usually when a person in a hospital is rendered unconscious and are operated upon, he has no recollection of even having been put to sleep. Frequently he asks when he's going to have the operation. He is surprised to find that it had already been performed!
Similarily, when we "awake" in the resurrection, we will have no memory of events between our death and resurrection. Our resurrection might take place hundreds or thousands of years later!
Jesus didn't go to heaven at death. He said to Mary, "Don't hold me. I have not yet ascended to my Father." So shall Jesus have the pre-eminence in being the first begotten of creation, and the first born from the dead, but not the first to go to heaven immediately at death?
It's also clear that no one went to heaven before Jesus' time, for He said, "No one has ascended to heaven, except the son of man who descended from heaven."
