Can one say that God creates Himself? His very being would then be a causal loop personified. Perhaps that's what He meant when He said that He is the beginning and the end.
In sending Jesus Christ to our world with the possibility of failure, could God have endangered his own being in the process?
Since God is all-powerful, could He also, if he chose to, cease to be? Since the universe has self-actualizing laws that He set in motion, does He have to continue existing for the laws He set in motion to continue functioning?
Once He ceased to be, could He recreate Himself again, and again? Out of nothing? Might eternity itself be an endless cycle of creation and recreation out of nothing? Might it be just that instead of it being one long, ceaseless reality without any beginning or any end?
If you accept this premise, then, conceivably, when Jesus Christ died and rose after three days as He said he would, in a sense, God ceased to be and recreated Himself by His own ability. Jesus said, "I have the power to lay down my life and to take it up again."
If He was able to live again by his own power, did he cease to be in the traditional sense of ceasing to be. Is death, or cessation of life, for an all-powerful being, drastically different from mortal and limited beings such as ourselves who were created?
Is heaven outside of the time-space continuum? If that were the case then normal entropy would cease to operate, as well as the carbon cycle. There would be no problem for beings to be eternal if time and cause and effect were suspended in a timeless reality.
