I was thinking, and I thought that sins and the psychosomatic might be linked. "The way of the wicked is like darkness; They do not know over what they stumble" - Proverbs 4:19 This is what I thought: God created a function in our brains that when we sin, psychosomatic issues will generate. When these start to generate, it becomes more difficult to engage in our actions without making error. The more mental conflict and spiritual conflict that we generate, the more we will stumble. Going against God's commandments can bring these issues to the background of our minds making us unsure of why we stumble... most likely because we are oblivious to the causes in the first hand. Sins may also generate cognitive dissonance, and the same can apply to any philosophy that goes against the 'philosophy of God' because they all end up conflicting with itself. This going against can cause us to stumble and while at the same time be completely unaware as to why we do. This may connect well with what happened to King Nebuchadnezzar when we left his kingdom and went insane. Psychosomatic trauma and cognitive dissonance must have multiplied in the same way that sins multiply. His consistent refusal to listen to God and to keep his kingdom, followed by the power he constructed for himself, all must have lead to a great accumulation of psychological distress. Just as man who gains great power will boast and keep his head in the clouds, this same man will eventually fall back down towards earth and end up being unhappy regardless of how 'great' he has become. This may explain why confessing our sins is so healthy for our psychological well-being. Either confessing to a stranger (confessional booth), friends, or directly to God through prayer.
We cause ourselves to hurt, because we know we're sinning? Or? We display symptoms and feel pain because the Spirit that lives within us is sickened by our sinning, maybe? Interesting subject!
