George lost his job at the bowling alley. He was the pin boy, the person who set up the bowling pins. The owner invested in a machine that worked faster than George. Thus, George had no more setting up to do.
Sometimes, I lose my personal bowling game. My thoughts stand like bowling pins. My job is to knock down the bad ones, any thoughts that set themselves against Christ.
When I knock them down, I take control of the game and win it. However, if I allow the setup of wrong thoughts and neglect to take them captive, I lose the game. Our wrong thought bowling pins keep popping up and we must continually knock them down. Thoughts become habits and habits become actions and we succumb when we would rather not. When we allow that set up in our minds, we are hoisting a sail, standing ready to catch the wind.
We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ. (2 Corinthians 10:5)
This is our weapon of fighting
For though we live in the world, we do not wage war as the world does. The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. (2 Corinthians 10:3-4)
