The only thing we really have control over is our thoughts. Thoughts create feelings. Feelings create action. Action creates results. We must take our thoughts captive and cast down negative imaginations and every thing that would exalt itself above the power of our God.
2Corinthians 10:3-5 KJV
For though we walk in the flesh, we do not war after the flesh: For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds; 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
