Definition of delusion: A delusion is a false belief that is based on an incorrect interpretation of reality. A person with delusional disorder will firmly hold on to a false belief despite clear evidence to the contrary.
As strange as it sounds, the above definition seems to be describing the world system and all the beliefs that go along within it. The word of God says that the heavens declare the glory of God and yet God is not believed or even acknowledged. Psalm 19:1 The heavens are declaring the glory of God, and their expanse shows the work of his hands.
When an unbelieving man wants to be a denier concerning the existence of the only wise God, then he himself chooses to be delusional in his response to the obvious facts of God's creation staring him in the face. God never debates with the unbeliever, whether God is or is not. God simply says to have a taste of Him and they will know where the blessing of life is. Psalm 34:8 Taste and see that the LORD is good; blessed is the one who takes refuge in him.
These people choose self-denial and self-delusion in order to live the way they want; without code in life or responsibility of life toward anyone or anything. They think they can protect themselves from hurts and grief by simply rejecting the responsibility of life that sometimes brings challenging and emotional events. They are basically saying, "I do not acknowledge God, therefore, I am free from His expectations of me." Rom. 1:21 Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened.
In the early 1980's I was ministering in the prisons of New South Wales, Australia. I met a lot of inmates who had convinced themselves it was the fault of others they were incarcerated. They sometimes rationalized that they had little to do with the fact that they had robbed the bank, stolen the cars, or had committed other crimes. They were always sorry for getting caught and if they had another chance they would not get caught the next time. This self-delusional conversation went on most of the time. When I did meet people who did take responsibility for their actions, the outcome was very different. When these people were released from prison, most of them had productive lives.
You do not have to be a criminal to be self-delusional. The fanatical religious can be as delusional as seen with Jim Jones to bin Laden. When there is a corporate scandal of immense thievery in the billions of dollars, self-delusion and greed are most often the reasons for the outright thefts as seen in corporate America over the years.
Government ministers who fall from grace per se as in their misconduct in office because of adultery, embezzlement, or hubris often are delusional because they think they are above the laws of their own country. They have talked themselves into thinking they can break the law of God and man without consequence.
Spiritual leaders who fall under similar circumstances think they have acquired some kind of spiritual get out of jail free card for their shameful actions. Gal. 6:7 Do not be deceived: God cannot be mocked. A man reaps what he sows. There is grace and forgiveness for all the above sins and thank God for that. However, there are consequences in life for all the choices that are made by each and everyone of us. Deut. 30:19 I call on heaven and earth as witnesses today that I have offered you life or death, blessings or curses. Choose life so that you and your descendants will live. Therefore, let us be forthright in our choices.
God asks us to have our minds renewed with the word of God because God's word is what will help us overcome deceptive visions of grandeur inspired by self-delusions. Rom. 12:2 Do not be conformed to this world, but be transformed by the renewing of your mind. Then you will be able to discern what is the good, pleasing, and perfect will of God. God's word strongly imprinted in our minds will help us know what God wants for our lives, because the word of God will eventually make its way to our heart and we will know what to do in life.
We do not have to be mesmerized by every whimsical and delusional idea that floats by. We can make intelligent decisions toward life and all the intricacies that it offers. We will be able to discern between good and evil and not crash our lives while trying to figure out difficult decisions. Heb. 5:14 But strong meat belongs to them that are of full age, even those who by reason of use have their senses exercised to discern both good and evil.In essence, we will be able to grow up in the Lord and in our thinking. 1 Cor. 13:11 When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things. Look for the wisdom of the Lord and grow in His grace. God is our hope and we need not be ashamed, because the word of God is the power of our salvation and life. Rom. 1:16 For I am not ashamed of the gospel, because it is the power of God that brings salvation to everyone who believes: first to the Jew, then to the Gentile. Believing in God's word is not delusional, it is righteous and good living. Amen.
