In Colossians 3, St. Paul urges his spiritual children to set their affections only on things eternal. How often our affections are directed to things that are fallen and non-eternal. And when we set our affections on the things of this world, we are so easily ushered into a life of unsettledness, disquietude, angst, and anxieties. Where we choose to direct the eyes of our soul is critical. St. Paul is teaching us that if we will cast our eyes upon Christ and the wonder of His Kingdom, the peace of Christ will reign in our lives.
