The Apostle Paul is here giving us a helpful mental grid, or, a way to view the world with a positive lens. This is much more than the power of positive thinking, this is the Word of God; this is God's revealed will that we are to by grace live out. May God help us to think about what is true, honorable, just, pure, lovely, commendable, excellent, and praiseworthy, to meditate on these things.
