There is a lot of research and evidence that suggests what we think about controls our experience of life, and shapes the people we become. In some of his final instructions to the Philippian Church, Paul speaks to them about their thought life. He instructs them to rejoice, to not be anxious about anything but to pray at all times, and to flood their minds with thoughts on “good, pure, admirable, praiseworthy” things.
Paul knows the difficulties facing the Philippian Church from the world around them, and those within the Church. He knows the kind of suffering they’re facing, and the hard work that staying united requires. He knows how difficult it will be for them to live as counter-cultural witnesses to the Kingdom of God in Philippi.
And so Paul wants to help them persevere through the difficulties. There is so much of our life that is out of our control. So he instructs them to take control of their thoughts. Choose to rejoice. Choose to be gentle. Choose to not let anxiety rule your mind. Choose to think on what is true and lovely and praiseworthy.
And in our culture, we may not have the exact some struggles as the Philippian Church, but the life of being a citizen of heaven in America is still difficult. Distractions call to us at all times. Our thoughts can easily be persuaded to move towards things that are unhealthy and ungodly. The desire to not remain faithful to our commitments to God and others are high. And so the call to be mindful of what’s in our minds is huge.
