1. Satan deceives the human race by corrupting the mind with ungodly doctrines in order to kill and destroy
By using subtilty 3834 or craftiness, satan  beguiled/exapataō  or deceived Eve with  ungodly doctrines in the Garden of Eden. He so by mixing God’s command or truth with error. Apostle Paul worried that false apostles would use the same strategies to corrupt the minds of the believers.
Corrupted  (phtheirō/G 5351)  means to defile. A human can be defiled by evil communications/company (1 Cor 15: 33 & Rev 18: 17) and by practicing ungodly lusts such as fornication (Revelation 19: 2).
The human mind can also be corrupted into believing ungodly doctrines which deny  the truth of our Lord Jesus (2 Cor 11: 3 & 4).
But I fear, lest by any means, as the serpent3789 beguiled 1818Eve through his subtilty 3834, so your minds3540 should be corrupted 5351 from  the simplicity 572 that is in Christ.
For if he that cometh preacheth another Jesus, whom we have not preached, or [if] ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with [him] (2 Corinthians 11: 3 & 4).

2. The corruption of the human mind/Noēma/ G 3540 – what is the mind in the text of 2 Cor 11: 3?
Noēma (G 3540) is the Greek word for mind in the text.  Synonyms include devices  (2 Corinthians 2: 11)  and  thought  (2 Corinthians 10: 5).  Related scriptures in which Noēma  is used show that when the  mind is corrupted by satan, he blinds the human being from seeing the truth of God (2 Corinthians 3: 14 & 2 Corinthians 4: 4).
Noeō  (G 3539), which is the root word for Noēma  reveals that the mind refers to the ability to understand and  perceive truth. From  Noeō   we  hear Jesus lamenting that the disciples’ minds were blinded –  hardened (Mark 8: 17) and unconverted (John 12: 40).  The scriptures also reveal that the corrupted or blinded mind cannot understand or perceive the meaning of:
  • parables (Matthew 16: 9 & 11)
  • prophecies (Matthew 24: 15)
  • the existence of God (Romans 1: 20)

Some of these scriptures relate to church people.  More to come. Blessings, peace, angelic prosperity and protection.
