Still more broadly the term is also used of those Christians who insist on extra-biblical standards of behavior and judge godliness accordingly. For some it is zippers instead of buttons. No hair touching the ears for men. No jewelry for women. No slacks for women. No movies. No playing cards. And so on it goes. I’m sure you’ve heard of them. Extra-biblical standards of behavior are used to measure godliness. Legalism.
Try to imagine it. You are playing a game of Monopoly, and your opponent throws a ten with the dice. Then he picks up his player marker and begins counting his steps. Immediately you realize he will land on the corner — “Go to Jail!” Well, he doesn’t want to land there, so he stops just one step short, on New York Avenue. Immediately you cry foul. But he responds indignantly, “I only stopped one step short. What’s the difference? Don’t be such a legalist!”
Will you feel ashamed? Will you now feel that you have been too persnickety and legalistic? Too careful to obey the rules? Or will you feel that you have been cheated?
To make the point another way, I have never yet met a parent who complained that his child was a legalist because he obeyed too much. In fact, it would be impossible for any parent to imagine how his child could obey too much.
Yet, find a Christian who is careful to obey God in everything, and we won’t have to look far to find another Christian to call him a legalist. What do we make of this?
It’s a word we all hate, but exactly what is legalism? Legalism is that attempt to establish or maintain a right standing with God by means of our own efforts. The Jews of Paul’s day, for example, thought they could be saved by keeping the law. Anyone claiming to be Christian knows better than that, but even among believers there is sometimes found that attempt to maintain a right standing with God by means of personal efforts. They seem to think that having been saved by grace they must maintain that salvation by works. Legalism.
