"Don't let anyone capture you with empty philosophies and high-sounding nonsense that come from human thinking and from the spiritual powers of this world rather than from Christ" - Colossians 2:8
There is real danger in letting our thinking and as a result of our thinking our worldview be shaped by forces in opposition to Christ. The word "capture" is really strong - Paul is saying that thinking driven by values rooted in something other than Christ and his word are actively dangerous. This doesn't mean - can't mean (Paul liked to quote nonChristian philosophers himself) - that we isolate ourselves from our culture and enter into a "Christian ghetto". But it does mean that we need to be incredibly careful about our intake.
Are the sources of info I am letting into my head - from Internet, TV, radio, books, magazines, etc - likely to strengthen my rooting in Christ or to weaken it?
Lord, thank you that the source of all wisdom and truth is found in Christ and his word. Even as I seek to understand my culture so that I can speak to it, help me to be very discriminating about what I allow my mind to think, my ears to hear, my eyes to see. I know that there is a spiritual battle going on for my mind. I pray that my thoughts will be increasingly captured by Christ!
