When being captive is a good thing:

"The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds...we take every thought captive to make it obedient to Christ." 2 Corinthians 10:4-5

I'm encouraged that winning over my thought life is possible. When those daydreams and distractions--or panic and worry--well up inside, God, teach me to wield these weapons of divine power. Through your strength, I can arrest, detain, and subjugate my wayward thoughts!
