We live in this world, but we don’t fight our battles in the same way the world does. 4 The weapons we use are not human ones. Our weapons have power from God and can destroy the enemy’s strong places. We destroy people’s arguments, 5 and we tear down every proud idea that raises itself against the knowledge of God. We also capture every thought and make it give up and obey Christ. ~ 2nd Corinthians 10:3-5
Another good one is.
“The Lord GOD is my strength [my source of courage, my invincible army]; He has made my feet [steady and sure] like hinds’ feet And makes me walk [forward with spiritual confidence] on my high places [of challenge and responsibility].” Habakkuk 3:19 (AMP)
It helps for me to recite this whenever my mind begins to wonder to a place of discouragement, sadness, or anger.
It’s literally mind over matter!
