Take the analogy but you don't have to take it so literal - we exist to God and Heaven like a character in a super realistic simulation or matrix/holodeck would exist to us, the programmer/coder.

To understand that heaven is the base reality and we exist in a sub-reality to it. The Bible says this reality will be rebooted and a new reality given to those of us who have been saved, right? Salvation is the promise that you will be saved, like your saved file/data, and will be saved forever to exist in a new reality God has planned for us.

Are we in God's computer - no, I'm saying the analogy for how the relationship is or works is basically the same. It is in this day of high technology that we can understand how our existence is no different than a being in a highly accurate simulation.

Now hearing that God know's all the hairs of your head - is on par with what we would expect in any of our modern games/simulations. How many miles walked, interactions/consumptions/achievements, etc. Jesus walking on the water - how hard would that be for you to do that in your program?
