Paul’s letter to the Philippians tells us that whatever we do, we should do it for the glory of God. Every action, every moment of rest, every initiative we take, ought to be done through the filter of loving God and others. To do otherwise is to miss the mark, and it might even mean sin. The beauty of the Great Commandment is that it understands that none of these four aspects of our being (heart, soul, mind, and strength) can be offered to God in isolation. To give God our whole activity, it requires a matter of the will (mind) and purpose (soul) and passion (heart). God really requires (and deserves) everything we’ve got.
