There is so much good stuff in this passage of scripture.
I. We need to remember that our fight isn't against flesh and blood. It is a spiritual battle.
II. The good news is that God equips us to fight the spiritual battles! We have His authority and His Word to equip us.
III. He gives us the strength to pull down the strongholds and every high thing that exalts itself against the knowledge of God!
IV. We need to bring every thought that isn't of the Lord into captivity to the obediance of Christ! This is the battlefield, our mind! When we align our thought patterns to the Word of God. Not every idea is from the Lord! Amazing, I know...
V. Then practice! Live day by day in righteousness and when you mess up go before the throne of God and take care of business and keep going!
