2 Corinthians 10:4 (For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;) 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;
If we’re to define high things as it relates to our thoughts, then they are thoughts that go against the knowledge of God and His Word. By the same token a stronghold is a fortified thought. Most likely it’s one that has been nursed, rehearsed and built up to the point where it also goes against God and His Word. The Bible tells us to have the mind of Christ (Philippians 2:5-8 AMPC), yet our past experiences can produce hindering thoughts that will prevent us from the wisdom and grace Christ provided for us. We have to get rid of worry and resentments-letting someone live rent free inside your head- by keeping our minds stayed on the Lord (Isaiah 26:3 AMPC). We can’t afford to have an emotional mind set because how we feel won’t change the Word of God. Concentrate on the Word that allows us to go to the Spirit side of things and focus on what we believe (Galatians 2:16 TPT). We can change the way we think, when we attend to His Word (Proverbs 4:20-22 AMPC) and give life to it when we speak it by faith. In doing so we capture those high things and tear down the strongholds that have been hindering us!
