God is sovereign, yes, but that doesn't mean that He desires certain or specific outcomes, as opposed to Him allowing us to learn from mistakes. Parents who intervene constantly on their children's actions, will create nothing but dependent and helpless offspring. A Parent must let children fall to some degree, in order to build them up.
I am a parent, and I agree that children must be allowed to fall.
The thing worth remembering with this analogy is that both a concerned parent trying to help his child grow, and an absent parent may both allow their child to fall. We can tell the difference between the two by looking not only at whether a child falling is a sign of bad parenting, but at their conduct over time.
A good father, for example, would surely be there to help support their child growing, to hold their hand when they're suffering illness, to tuck them in each night and help them learn the lessons of the day.
I am by no means a perfect father, but I'm present in my children's lives. So sure, I would let them fall in certain situations. But there are others where I would not.
Man's spirit transcends the flesh, and dictates his action more than his brain. The evidence is axiomatic.
I mean...you can make whatever statements you like, but they're opinionative. There is nothing self-evident about man's spirit transcending flesh in anything more than a metaphorical sense. Meanwhile, there are plenty of studies that can link changes in cognitive behavior to brain damage, for example.
Your understanding of psychology, this pseudo science, does not address the issue, or penetrate to the catalyst behind man's behaviour.
I would basically agree it's a pseudo-science. That elevates it to being more predictive of human behavior then demonology. But still, it's certainly not capable of answering all questions around cognition.
Jealousy, greed, avarice, lasciviousness, arrogance, hate, etc cannot be quantified or psycho-analyzed.
They can be psycho-analyzed. That you don't agree with those findings is a different thing entirely, but I can link you to plenty of research on the topic. However, I suspect that wouldn't be of interest, so I'll hold.
The spirit knows things that the flesh is unaware of.
I have no issues with people who believe such things, unless they insert them into (for example) medical practice.
