Taking every thought captive

“We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedience to Christ.” 2 Corinthians 10:5
Controlling our thoughts is one of the hardest things to do. Controlling our actions is much easier. Jesus alerted us to this in Matt. 5:28 by saying that indulging in lustful thoughts is as bad as committing the act itself.
Have you noticed how a train of thought can so quickly degenerate – even during prayer, or worship tim? One minute you can be thinking about spiritual things, and before you know it, your mind has wandered to what to have for lunch. Such thoughts are not necessarily sinful, but they are spiritually unproductive.
It takes self-control and discipline to be aware of our thoughts. There are certain things that as Christians we should not think about. We need to be diligent in our thought life: any thought that does not glorify God should not be indulged. And any thought that is disobedient to Him should be cut off at the source.
God knows all of our thoughts. He also knows when we are striving to think right. Sometimes we can’t help thoughts that come in – much as we can’t help some of the things we inadvertently see – but we can keep ourselves from indulging them.
