It’s all too easy to turn the fight of faith into sanctification-by-checklist. Take care of a few bad habits, develop a couple good ones, and you’re set. But a moral checklist doesn’t take into consideration the idols of the hearts. It may not even have the gospel as part of the equation. And inevitably, checklist spirituality is highly selective. So you end up feeling successful at sanctification because you stayed away from drugs, lost weight, served at the soup kitchen, and renounced Styrofoam. But you’ve ignored gentleness, humility, joy, and sexual purity.
