I’m currently considering what the mind may consist of. Is it all neurons and synapses, as the materialists insist, or is it an immaterial spirit within us? Is it perhaps a combination of both?
I see the brain as a physical interface between our spirits and the material world we live in. It also operates and maintains our body, and communicates with people and things around us. We need both brain and spirit to be who and what we are in this material world, and the mind is involved in both.
Descartes was one of the first famous philosophers to consider such questions, and is frowned upon in our time for, well, believing in God, and for concluding that the mind and the physical body are two separate things. The mind cannot be measured he reasoned, therefore it is not physical.
Whatever the mind is exactly, we know from Scripture that God knows it, and knows it better than we do:
You have searched me, Lord,
and you know me.
You know when I sit and when I rise;
you perceive my thoughts from afar.
You are familiar with all my ways.
Before a word is on my tongue
you, Lord, know it completely (Psalm 139:1-4)
I know I’m not the first to make the computer-human analogy, but thinking about it, there really are a lot of uses for it in our reasoning. Our body is the hardware, and our mind and our spirit is the software. Just as we can copy and paste on our favorite devices, and just as we back up our information so that nothing is lost, so God must have a copy of our minds, and of exactly who we are. Of course, with limitless intelligence, He can keep that copy within His own mind: He doesn’t need any hardware. I’m speaking metaphorically here. And we know that “God is spirit” (John 4:24).
Our Creator surely also has a copy of our DNA. So when we die, He can take His back-up of our being-our own human nature and character, and upload it into a brand new fleshly version of our body, created from our own (but corrected) DNA code. Voila: resurrection! It’s a glorified version of taking a software design of, say, an aircraft, and turning it into the real thing.
Unwanted, corrupted codes, which God calls “sin” will be discarded; deleted (1 Corinthians 3:14-15). Then what remains will be that in us which has loved Him and His ways, and which has lived for Him, and also no doubt, the degree of our individuality which is uncorrupted.
In that case, how much of you, of me, will be left after deletion? If your “codes” are all corrupted, and your hard-drive intrinsically flawed, you are of no value in God’s universe, and you certainly cannot restore yourself. Scripture says that all humans are fatally flawed in their software and their DNA, which is why we die. We desperately need a re-boot in this life: we must be born again, spiritually speaking. And ultimately we need a complete re-build. The living Word of God is the antivirus that we all need. And in God we can have all our corrupted codes re-written. On top of that, the operating system upgrade will be positively out of this world! Glory to God!
