I like to fish, and there are lots of ways to do it. Fly-fishing a mountain stream is a precision technique that focuses on a specific target. Tossing cut bait into salt water is a more indiscriminate method that produces a variety of results.

Industrial fishing is a whole different approach. Large commercial trawlers can haul in as much as 500 tons of sea life a day. Their huge nets randomly scoop up everything in the ocean. Of course, this approach requires some serious sorting.

If we’re honest, our minds are a lot like commercial trawlers. We’re exposed to a constant flood of images, information, and agitation throughout the day. As such, we end up with all kinds of thoughts in our brains… good, bad, and ugly. We need to be careful about what we’re “catching” and thoughtful about how we’re “sorting.”

Here’s a parable Jesus told…

“Once again, the kingdom of heaven is like a net that was let down into the lake and caught all kinds of fish. When it was full, the fishermen pulled it up on the shore. Then they sat down and collected the good fish in baskets, but threw the bad away” (Matthew 13:47-48).

The adage “how you think determines how you live” highlights the powerful connection between our thought patterns and our overall lifestyle and well-being. The quality and nature of our thoughts significantly influence our choices, actions, and reactions.

The Apostle Paul declared this mission: “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).

“Taking every thought captive” involves more than human effort, but it certainly includes that. Nothing worthwhile happens apart from the Spirit of God actively working in and through us, but we must choose to actively participate.

Paul told the Corinthians he was earnestly fighting with “divine power” against an ungodly worldview to “demolish strongholds” that oppose the knowledge of God.

The “Rule of Exposure” is simple and profound: what you’re exposed to the most shapes your thoughts. Think about your screen time. What are you reading and watching? Who are you spending most of your time with?

Attention determines direction. We naturally move toward whatever we focus on. It’s called “Target Fixation.” That’s why when you’re driving you shouldn’t stare at the cliff you’re trying to avoid. Instead, “set your heart and mind on things above” (Colossians 3:1-2).

Martin Luther said, “You can’t keep a bird from flying over your head, but you can keep it from building a nest in your hair.” We can’t control everything around us, but we can control what we focus and reflect on.

“Whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable – if anything is excellent or praiseworthy – think about such things” (Philippians 4:8).
