Then I applied myself to the understanding of wisdom, and also of madness and folly, but I learned that this, too, is a chasing after the wind. Ecclesiastes 1:17
Thinking something is true that is not true about God can hurt your heart and in turn your mind and brain.
Should the absence of truth lead to a damaged mind and brain, no amount of medical intervention will of itself remove the absence of truth.
Furthermore, just as they did not think it worthwhile to retain the knowledge of God, so God gave them over to a depraved mind, so that they do what ought not to be done. Romans 1:28
An ounce of prevention is worth a pound of cure.
Only be careful, and watch yourselves closely so that you do not forget the things your eyes have seen or let them fade from your heart as long as you live. Teach them to your children and to their children after them. Deuteronomy 4:9
If you have a damaged mind and brain and this is resulting in actions and speech that cannot consciously be controlled, medical intervention can provide a temporary way to remove the outward symptoms of a damaged mind and brain. This is done not to cure your mind and brain, rather to "buy you time" that can enable the removal of what has caused the hurt in your heart in the first place.
Julius Ceaser ---“Experience is the teacher of all things.”
Just because someone has labelled you a cripple doesn't mean to say that you are a cripple.
Just because someone has said you have a broken leg doesn't mean to say that your leg will not recover.
Just because you have a broken leg doesn't mean to say that you shouldn't use a wheel chair. Just because you use a wheel chair doesn't mean to say your leg will not recover.
