He is no doubt, the source of life. All life came from Him and only by His eternal spirit we could maintain our existance. Bu what defines life? For being in hell is often called eternal death, but one is very much alive there to suffer and toil.
When Adam and Eve ate the fruit, they died, but they are very much alive physically. So there must be something else that dies besides the flesh. Well, what we can see from Adam’s story is that although his flesh lived, he has no more fellowship with God, he still talk to Him, but there is no more strong relationship between them.
Genesis 2:17 (NET) but you must not eat from the tree of the knowledge of good and evil, for when you eat from it you will surely die.”
Do not fear death. It may be essy for me to say, i know. But really, the only thing we should fear is not being in the presence of God. We often judge a place as bad or uncomfortable, this place is scary and that place is noisy. But as long as we can still live that is because the presence of God dwells there.
There is one place that has no presence of God. That place is hell.
So what do we do? Want to stay alive? Stay in the presence of God.
