2Corinthians 10:5 casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ; KJV
The phrase "high thing" is from the Greek word 'hupsoma'. The simple literal meaning refers to something elevated above the earth. E.g., Mountains, hills,etc. This definition is quite easy but Paul meant something deeper which his audience understood clearly. The term "hupsoma" is an astrological term denoting a location above the earth associated with supernatural events and beings. This is where horoscopes are set forth. All the zodiac readings you read about are believed to come from the space above the earth. It is safe to conclude that when Paul talked about "high things" in context of the opening scripture, he was referring to demonic powers operating above the earth that work on people's minds. They seek to manipulate men by making them believe the wrong things.
The greatest warfare starts in the mind. There are believers who still believe in zodiac signs. They read what astrologers received from "high places" to determine the course of their lives. I'm appalled when I see believers claiming they have a particular trait based on zodiac readings. The devil doesn't stop there, when he wants to put people in demonic bondage, he starts by preaching the wrong sermon to them. The moment they believe those things, an unbiblical mental stronghold is built in their minds. From there, the devil begins to torment them.
Paul called those wrong beliefs "High thing that exalteth itself against the knowledge of God". You need to rebel against anything you believe that is not in full agreement with the knowledge of God. What an astrologer says about you is not valid when compared with what God says about you in His word. How do you win this battle? Paul said, " casting down imaginations....bringing into captivity every thought to the obedience of Christ". You can achieve these two by feeding your mind with God's word, renouncing contrary beliefs, confessing God's word and dealing with cosmic powers seeking to manipulate your mind.
Father, I receive freedom from wrong mental stronghold the enemy is using against my life in Jesus name.
