Mind is not Material
1, If mind was the brain or any material there would be no free will, as if your decisions, actions, plans, and all cognitive functions depended on mindless matter than you'd have no free will at all so it's,
1, No Director(Mind)
2, Material Director, which is basically 1, No Director, as flucuations of material(plural too, thousands of cells) has no director
3, Immaterial director where you can freely choose to do as you please, since we do have free will and can do as we please, Option 3 is the only choice.
2, Color is not material, even blind can see(black is something)
3, See the text on this screen, Physically, what is it? Just energy on the screen, there isn't anything physical about Information/Data
4, Thoughts are not material
5, Scientific Fact, Every cell in your body dies and regenerates(like skin), that by every 7 years, you are a brand new material being, however you are the same exact person, how can that be if you are material?
It would be an impossibility, you are the same person yet are completely materially new, so Factually there is a property to you(The mind) that isn't material.
when you talk to someone, are you talking to flesh or a person? Talking to God(The Father, The Son, and The Holy Spirit) is like talking to anyone else.
Also here is something mind blowing,
1, Factually you are not your hands or nerves in them(we could chop off your hand you won't feel the hand or the nerves in them again, you'd still exist)
2, if mind is brain(that is material), then it would be impossible to feel my hand.
If pain is caused by brain signals hitting the hand then I won't feel it as I am not my hand.
If pain is caused by hand signals going to the brain I would feel the pain in my brain.
Now, hit your hand, where did you feel it? in your hand correct?
There you go, you are an Immaterial being, as if you were your brain or any material, you would be incapable of feeling your hand. you feel your hand, yet you aren't your hand and no properties of your hand are you, there is therefore an immaterial part of you(basically, just you) that causes you to feel your hand.
Have no fear, Theology and The Bible is here, you'll never lose your faith.
