1 Peter 1:15-16 is what I thought of when I read this great article by Josh:
The longer I am a Christian, the more keenly aware I am of my need for God’s grace. We are supposed to “bring every thought into captivity to the obedience of Christ” (2 Corinthians 10:5), and I believe this to be my greatest failure as a follower of Jesus. We are supposed to have a filter—a kind of screening process our minds use to dismiss material that is not going to be healthy for us to think about. Philippians 4:8 describes the standard: “Whatever is true, whatever is honorable, whatever is right, whatever is pure, whatever is lovely, whatever is of good repute, if there is any excellence and if anything worthy of praise, dwell on these things.” Using this set of requirements, we should probably dismiss MOST of the things we encounter on a daily basis as food for thought. I struggle to do this. There are images or ideas that enter my mind at times, and I know immediately that they are unhealthy for my spirit, yet I allow myself to follow them out. And, just like a mature tree is harder to remove from the ground than a sprout (and leaves an uglier spot in the ground once removed)—or just like the cooking dish is harder to clean after it has dried for hours—a thought process is harder to avoid once you have allowed it to take root in your mind. Once those neurons carve out a new path, they like to return and travel it again.
God, help us to apply the filtration process in Philippians 4:8 to keep our brains free of the kind of trash that tends to lead us away from Christ. – Joshua Gulley
