Ancient Platonists seemed to believe that matter is evil. In Plato's Phaedo, Socrates tells his friends that he's eager to leave his body because, in the afterlife, bodily needs won't distract him from philosophy. He wants to spend the afterlife talking with other philosophers. From what I can tell we won't need to tolerate bodily distractions in heaven. We'll be able to eat, but we won't need food. We likely won't need restrooms either. So I feel empathy for Socrates.
Dr. William Lane Craig, the brilliant Christian apologist from Biola University, is a substance dualist who believes that he is his soul. So his substance dualism is like Plato's substance dualism. But Dr. Craig knows that matter isn't evil since he knows that God creates it. St. Augustine was a Platonist who condemned heresies that said matter was evil. My point is that Platonism and substance dualism aren't evil in themselves. But some Platonists drew false conclusions from Platonism when those conclusions didn't follow from it.
My acquaintance's seeming pride troubles more than his theory does. He believed that he's the first person to interpret Genesis accurately. That's news to Our Blessed Lord, the second Person of the Holy Trinity since he and the other two divine Persons inspired each book of Holy Scripture. Then again, my acquaintance may believe that he's the only human person to interpret Genesis accurately.
My acquaintance became a home-aloner because his Baptist pastor disagreed with his theory. Soon after that, another pastor invited my acquaintance to publish is theory because that pastor wanted to teach it to his congregation. If I remember correctly, my acquaintance thought God revealed the theory to him after his nearly deadly motorcycle crash. I don't know about you. But I don't think it would be rational to believe just any old thing that popped into my mind after a severe head injury.
Well, I could be wrong about this
but it's not that we won't have needs, God created us to have needs but God has created providence for those needs. It is reason to be thankful and praising the Lord when we have a need, and God provides for it, it deepens love for God. It's like why the fall and redemption? Because it increases dependence on God and deepens love for Him that He is your redeemer.
Now, I know people will point to something like this
Revelation 7
13 And one of the elders answered, saying unto me, What are these which are arrayed in white robes? and whence came they?
14 And I said unto him, Sir, thou knowest. And he said to me, These are they which came out of great tribulation, and have washed their robes, and made them white in the blood of the Lamb.
15 Therefore are they before the throne of God, and serve him day and night in his temple: and he that sitteth on the throne shall dwell among them.
16 They shall hunger no more, neither thirst any more; neither shall the sun light on them, nor any heat.
and say see? no more biological needs
but to that I point to the next verse:
17 For the Lamb which is in the midst of the throne shall feed them, and shall lead them unto living fountains of waters: and God shall wipe away all tears from their eyes.
It's not that they don't still have needs it's that they do not have
unmet needs. see the first word, "for". The never hungering or thirsting is not because God removed the needs.... it is because God provides for those needs till their cup runneth over. Nobody would starve because nobody would ever have a lack of Providence.
That was how it was in the beginning. God provided, no needs unmet. The curse involved things not coming forth abundantly but now had to be worked and labored for
Revelation 21
5 And he that sat upon the throne said, Behold, I make all things new. And he said unto me, Write: for these words are true and faithful.
6 And he said unto me, It is done. I am Alpha and Omega, the beginning and the end. I will give unto him that is athirst of the fountain of the water of life freely.
7 He that overcometh shall inherit all things; and I will be his God, and he shall be my son.
Romans 8
32 He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things?
Let's break this one down too
Many people say "Jesus is the reward, you don't need anything else"
But that's not the promise. The promise is WITH Jesus God provides everything else too freely.. it brings me back to..
Matthew 6
31 Therefore take no thought, saying, What shall we eat? or, What shall we drink? or, Wherewithal shall we be clothed?
32 (For after all these things do the Gentiles seek
for your heavenly Father knoweth that ye have need of all these things.
33 But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you.
Most people just think this has to do with Providence in this life, but to be frank, there are Christians who starve or die of dehydration or exposure. It does happen. The promise is fulfilled in the next age, after the resurrection, in the Kingdom of God, that is where God provides for all needs.
People think God provides now but..
I think we don't even know the tip of the iceberg of what Providence from God is actually like.
