“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;”
‭‭2 Corinthians‬ ‭10:5‬ ‭KJV‬‬
The strong holds that are most difficult to pull down are those in our own mind. Those evil imaginations God’s Word constantly warns us about. Those doubts and areas of unbelief towards God. God’s goal for us is that our every thought be brought into obedience to Christ.
