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
Watching what you think is a true discipline. Not allowing your mind to wander into areas it has no business in. You have to ‘capture’ your thoughts or in other words don’t allow wrong thinking to occupy your head.
Yes it takes discipline and practice and the more you occupy it on uplifting things or profitable endeavors the less you will find yourself needing to rein it in. Keeping it focused on ‘things above’ meaning what is good, pure, perfect and wholesome. Not filling it with pornographic images, lewd jokes, bad movie or TV or reading trashy novels or gossip magazines and tabloids.
Remember Jesus lives in you and knows what you are doing. Take time each day to pray and read scripture and run from evil. This will help you capture wrong thinking.
PRAYER: Lord I want to think good things and not conjure up stuff or get involved in gossip or junk that doesn’t do a thing for the kingdom of God. Give me strength to acquire this discipline. In Jesus’ name. Amen.
