When we reject God, we reject ourselves and our dignity. When we harden our heart and mind against the knowledge and awareness of God, we blind ourselves to life itself! Paul explained it like this:
· They exchanged the truth of God for a lie, and worshiped and served created things rather than the Creator--who is forever praised. Amen. Because of this, God gave them over to shameful lusts... Furthermore, since they did not think it worthwhile to retain the knowledge of God, he gave them over to a depraved mind, to do what ought not to be done. (Romans 1:25-28)
When we reject God, we have to replace Him with something else as supreme. Some may call their God-substitute the “human spirit,” “the will to power,” or merely “captains of our own ship.” In any event, we have done the very thing that the Bible warned us against - We have “worshiped and served created things [namely ourselves] rather than the Creator.”
As a result, God has given us over to the very thing we wanted - a “depraved mind!”
Let me just offer one example of how we have mentally degraded ourselves and have reaped confusion. Atheists consider themselves “freethinkers.” Meanwhile, by rejecting God and any spiritual reality, they have condemned themselves and have adopted materialism – the belief that everything is merely energy and matter, the stuff of science. Consequently, their thinking is also just a matter of chemical-electrical reactions.
However, if thought is no more than chemical reactions, there is no room left for freewill, let alone, free thought! While they want to believe that they can think freely, they have denied this possibility when they rejected God. They have deprived themselves of any meaning, purpose and dignity when they rejected their Source!
