Most of us struggle with one or more of our passions: anger, love, sorrow, desire for food or drink, desire for sexual intimacy, desire for possessions, desire for popularity, and so forth. None of these is inherently wrong; indeed, they are good as they come from the hand of God. They become sinful when focused on the wrong object or when they become excessive. The key is to learn to master them through moderation/self-control and by focusing them on the purpose for which they are intended.
This year’s John Lewis Christmas commercial features a young fire-breathing dragon who, though not fierce, has an ability that he cannot seem to control. He must learn to use it only at the proper time and for good purposes. Allow his ability to breathe fire to represent a passion (e.g., anger, love). Observe the damage caused when this passion is uncontrolled or focused on the wrong things, but also observe the blessing brought when the young dragon learns to master it and use it for a good purpose.
