It's true. We are all losing our minds. Literally going insane. The root cause is spiritual adultery. What is that?
God provides a physical example along with the consequence in Proverbs 6:32, "But whoso committeth adultery with a woman lacketh understanding: he that doeth it destroyeth his own soul."
This "destruction of the soul" is literally insanity. It is the total corruption of the mind through the indulgences of the flesh. For the sinner, this cannot be helped. Is it no wonder that the world is mad? For the Christian however, the effect is the same although the Christian has the power to not sin and therefore stop the process of mental decay due to sin.
God tells us in Romans 7 with another physical example regarding marriage how it translates into spiritual reality. The physical marriage between man and woman is compared to the spiritual marriage between man and the law. So it is with adultery.
When we commit sin, we commit adultery. Why is this so? Because as Christians, we are betrothed to Jesus. According to the ancient culture and Word of God regarding this reality as pictured in Ephesians 5:25-27, our betrothal is as good as being married, even though the consummation is yet to come.
Therefore, to go back to the world, commit sin, or live under the law is adultery against our Bridegroom, Jesus Christ. The result is the destruction of the mind.
But where sin did abound, there did grace much more abound. And we have the advantage over the world of getting our minds back. Here's how God does it:
"He restoreth my soul: he leadeth me in the paths of righteousness for his name's sake." - Psalm 23:3
"For of him, and through him, and to him, are all things: to whom be glory for ever. Amen. I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service. And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God." - Romans 11:36-12:2
So you see, God restores our soul (mind) in righteousness. In addition, we must purposefully renew our minds through living sacrifice.
I can personally testify to the reality and efficacy of this Word. I destroyed my mind with sin (things that are not even to be spoken of) until God saved me at age 18. Since then, He restores it and I renew it daily. It is not of works but grace alone. Praise God.
I remembered another verse that is quite important and relevant here. Concerning wisdom and its personification of the Lord Jesus Christ, God says in Proverbs 8:36, "But he that sinneth against me wrongeth his own soul: all they that hate me love death." Here again is another very powerful statement regarding the effects of sin on the mind.
That word "wrongeth" literally means to do physical damage to. Sin destroys those little gray cells! This is something no medicine can cure, no drug can alter, no potion can diminish. Only the blood of Jesus can wash away all that sin and only then can God begin to reverse the effects.
