Quellycatface, here’s my take on it, for what it’s worth. Don't know whether you watched Dr. Oz recently when he did his show on out-of-body-experiences? All those he interviewed had similar experiences. Pleasant thoughts, out-of-body senstation (watching yourself from afar), tunnel, bright light, etc. Researchers ascribe these sensations to a lack of oxygen as the brain is starting to die. But they emphasize that not all parts of the brain die immediately. Some last longer than others. They tested whether these people, e.g., those that had cardiac arrest on the operating table, have a real out-of-body experience by putting a picture of someone famous on top of the surgical lights. No one reported the picture, so they concluded that it was not a real out-of-body experience, but only the sensation of an out-of-body experience.
I compared above to what the Bible had to say:
Then the dust returns to the earth just as it happened to be and the spirit itself returns to the [true] God who gave it. (Ecc 12:7 NWT)
And during that time your people will escape, every one who is found written down in the book. (Dan 12:1 NWT)
And when he opened the fifth seal, I saw underneath the altar the souls of those slaughtered because of the word of God and because of the witness work that they used to have. (Rev 6:9 NWT)
For here I am creating new heavens and a new earth; and the former things will not be called to mind, neither will they come up into the heart. (Isa 65:17 NWT)
So, for God to be able to resurrect you, he needs a back-up of you (as you regularly need to back-up the work on your computer in case of a hard disc failure). In the Bible, death is compared to sleep. When you sleep, your brain does a back-up of your day’s activities and thoughts. As the Creator he would have access to your back-up. When you die, a back-up is made of your life and personality. This back-up he then transfers and stores in heaven. If you die a horrible death and your brain is damaged, he takes the previous night’s back-up. In that case you will not remember how you died. That part is not recorded in the back-up.
This is what I believe in a nutshell. This I will continue to believe until I am proven wrong, which won't happen in my lifetime...
