The Bible tells us plainly that death means a loss of consciousness, and a loss of life:



'Though this understanding highlights how horrible death really is, it also should alleviate our fears about it. No matter how painful a method of death is, no matter how many unresolved issues you leave behind, no matter how scared of the dark you are, at the moment of death you will cease to be aware of anything, even your own death. Just as you can never tell the moment you fall asleep, so too death is nothing to fear.'
