The natural mind of man, even at its best, has many infirmities and deficiencies from which it needs to be delivered. In relationship to God, the source of all true peace and joy, it is in a contrary and rebellious condition. The mind of the flesh is hostile toward God, and it is utterly unable to be subject to the law of God (Romans 8:5-7). The natural mind rejects the true teachings of God because they are foolishness to it (1 Corinthians 2:14). When people are unable to believe the Gospel of our Lord Jesus Christ, it is because satan as the god of this world has blinded their minds (2 Corinthians 4:3-4).
The mind must be changed!
Until the mind is changed, a person lives in the lusts of the flesh, “indulging the desires of the flesh and of the mind” (Ephesians 2:3). He walks in a mental mirage and in darkness of understanding which excludes him from the life of God (Ephesians 4:17-18).
Unless the mind is changed, a man is unable to lift his thoughts above the pleasures and the problems of daily living. His mind is entirely occupied with material concepts. This is one of the factors which makes a man in his natural state unfit for heaven. If he were somehow to get into heaven in that condition, it would be unending torment for him!
The mind must be changed! This is what the Bible declares, for it is written, “God is now declaring to men that all everywhere should repent” (Acts 17:30). The Greek word translation of the word “repent” primarily means “change one’s mind.” Repentance is that voluntary change of mind in the sinner in which he turns from sin. It involves the recognition of a sinful and lost condition. It will results in believing the good news that Christ died for our sins, that He was buried and rose again from the dead, and that He lives forever to save those who call upon Him. Thus is accomplished the work of regeneration, and with it the mind undergoes a drastic change.
People who are lost have been known to imply that the enthusiastic Christian is “not right in the head.” Truth is that it is the other way around. In the story of the Prodigal Son, it was “when he came to himself” that he decided to return to his father and confess his sin (Luke 15:17-19). It is the person who is out of right relationship with God who is “beside himself”. A young lady became the butt of criticism by her friends after sh had trusted Christ as her Savior and began to live for Him. It was even suggested that she was “cracked in the head”. When she heard of this, she made the wise comment, “If I am cracked in the head, that must be where the light got in.”
The mind must be changed!
When a person has been born again further correction and continuing corrections are still needed for the mind. As someone said, “It is possible for a child of God to have a new life and a new heart but be without a new head.” It is not uncommon to find faithful Christians who are narrow-minded and filled with prejudice. Not a few have minds which are contrary, deceived or passive.
