My dear brothers and sisters, take note of this: Everyone should be quick to listen, slow to speak and slow to become angry, because human anger does not produce the righteousness that God desires. Therefore, get rid of all moral filth and the evil that is so prevalent and humbly accept the word planted in you, which can save you. Do not merely listen to the word, and so deceive yourselves. Do what it says. Anyone who listens to the word but does not do what it says is like someone who looks at his face in a mirror and, after looking at himself, goes away and immediately forgets what he looks like. But whoever looks intently into the perfect law that gives freedom, and continues in it—not forgetting what they have heard, but doing it—they will be blessed in what they do. (James 1:19-25)
How are the de-formed desires of our flesh re-formed in the ways of Christ? James has some thoughts.
When talking about the righteousness God desires, James seems to say: if we don't have the capacity to listen to the person sitting in front of us, if our words sometimes fly out unchecked, or if our temper controls us more often than we control it—if that's how our day to day life looks in relationship to others—then how can it be any different in our relationship with God (and vice versa)?
Our daily life and our spiritual life have a lot in common, and so practicing things like listening more and speaking less in our relationship with God helps us do the same in our relationship with others and vice versa. That's because the practice slowly forms our desire to really listen and hear well in all of life.
As it is with any human endeavor, beginner's luck and raw talent only get you so far. Most of us play like we practice, and practice is hard work! There's not a professional athlete out there who hasn't done thousands of times already what you'll see them do on the court, field, or rink in competition. That's why they're good at it.
Habitual repetition is how muscles learn their movements: it's also how our heart, mind, and soul learn theirs. Repetition of the actions of loving another person, like confessing, forgiving, and reconciling with that person is the way of training ourselves not only how to love someone, but it also trains our desires to want to love someone in just that open, honest, reconciling way.
When it comes to training our desires, you really do have to fake it 'til you make it. Which is what that habitual repetition of practicing something is all about. That's why God commands it—so that we do practice these things and get them into our bones.
It's only those who know the rules of the game, the boundaries of the field, and who have disciplined themselves in the fundamentals who are free to play and enjoy it to its absolute fullest. That's true whether you're talking about athletes, tradespeople, jazz musicians, or Christians.
So look into God's perfect law that gives you this freedom and continue in it. Don't forget what you've seen and what you've heard there—but do it. Practice it with your friends. Practice it with your families. Practice it with your God. You'll be blessed if you do. Indeed, you might eventually even find yourself wanting, or desiring, to do these things.
Of course, all of this comes through the work of the Spirit who sanctifies us and empowers us to practice what God calls and commands us to. He slowly conforms us, our lives, and our desires to the likeness of Christ and forms fruit within us: like gentleness, love, and self control.
That's what it's about—becoming, through the power of the Spirit at work within us, more and more from our desires up, who we already are in Christ.
