According to the words of Moses, sin is crouching at your door. Crouching is a position where the knees are bent, and the upper body is brought forward and down, sometimes to avoid detection or to defend oneself: If sin is still crouching at your door in 2023, you might as well get all the way down on your knees to start fighting back spiritually. The earthly brother of Jesus clarifies that this has nothing to do with God. Rather, unwholesome thoughts come from desires, enticement and lust, James 1:13-15.
But for [a]Cain and his offering He had no respect or regard. So Cain was exceedingly angry and indignant, and he looked sad and depressed. 6 And the Lord said to Cain, Why are you angry? And why do you look sad and depressed and dejected? 7 If you do well, will you not be accepted? And if you do not do well, sin crouches at your door; its desire is for you, but you must master it, Genesis 4:5-7.
According to the temptations of Adam and Eve in Genesis 3 and their son Cain in the passage above, the process of sin begins with an unwholesome thought that enters your mind, James 1:14-15. The serpent tried to convince Eve that God was holding her back by prohibiting access from the Tree of Knowledge. Meanwhile, envy and jealousy were putting thoughts into Cain’s head about eliminating the source of his frustration. Despite God’s warning in the passage above, Cain acted upon the unwholesome thought that remained in his mind.
For though we walk (live) in the flesh, we are not carrying on our warfare according to the flesh and using mere human weapons. 4 For the weapons of our warfare are not physical [weapons of flesh and blood], but they are mighty before God for the overthrow and destruction of strongholds, 5 [Inasmuch as we] refute arguments and theories and reasonings and every proud and lofty thing that sets itself up against the [true] knowledge of God; and we lead every thought and purpose away captive into the obedience of Christ (the Messiah, the Anointed One), 6 Being in readiness to punish every [insubordinate for his] disobedience, when your own submission and obedience [as a church] are fully secured and complete, 2 Corinthains 10:3-6.
The apostle Paul provides a solution to stopping unwholesome thoughts from polluting your soul in the passage above. If Lucifer is a fallen arch angel who is ruler over the air on earth, Ephesians 2:2, physical means of protection will only go so far. The best way to stop unwholesome thoughts from staying in your mind is by using the armor of God, Ephesians 6:10-20. When these spiritual weapons are exercised daily, God will shield you from the Devil’s attacks. As Christians use prayer as a vehicle to put on each piece of spiritual armor, your thought life will become obedient to Christ, causing unwholesome thoughts to flee.
