Recently, especially in response to the revelations of particularly egregious misconduct by Ravi Zacharias, and even abuse, we’ve been warned away from saying anything akin to “There, but for the grace of God, go I.” What is, to some an admission that, as my colleague Shane Morris has put it, everyone is made of the same clay, is, to others, excuse-making cloaked in faux humility. To them, it suggests that sexual sin, even the most terrible kind, is inevitable for men, so we shouldn’t expect any better. Or, to put it differently, if only God’s grace stands between us and horrific sin, we don’t need to take responsibility for avoiding sinful behavior. In the end, it’s up to God, and, in the end, the horror suffered by victims is downplayed.

Though none of these things is, in my view, necessarily implied by saying “there, but for the grace of God, go I,” the concerns are valid if for no other reason than an observation Chuck Colson often made, “There is no limit to the human capacity for self-rationalization.” Even our admissions of guilt can be, he knew, attempts to rationalize our behavior.

There is an important truth about our propensity for sin no matter which slogan we use. In fact, the Bible repeats this in various ways. Proverbs 4 says, “The way of the wicked is deep darkness; they do not know over what they stumble.” In other words, we can surprise ourselves with our sin. After all, our “hearts are deceitful above all things,” the prophet said, “and desperately wicked. Who can know it?”

The Bible is full of this wisdom. At the same time, these verses are not excuses. It’s precisely because our own sin can so surprise us, that we should be cautious and beg God for protective grace, even to the point of metaphorically cutting off our limbs and gouging out our eyes, should it come to that.

In recent weeks, we’ve learned of abuse committed on a staggering scale, but it didn’t come from nowhere. It came from a long-term trajectory of compromises made possible by a perfect storm of failures – of accountability, of honesty, of tolerating, hiding, and abetting temptation. It is a gift of God that so few of us are in such a position to commit evil on this scale.

I doubt that anyone who says “there, but for the grace of God, go I” is suggesting they’re mere inches away from doing the exact same thing as we’ve learned about Ravi Zacharias. That’s because it’s doubtful that anyone intends to sin on a grand scale.

Back in the age of Saturday morning cartoons and “Just Say No!” public service commercials, there was one ad where, as the screen flashed images of a down-and-out drug addict, the announcer would proclaim, “No one dreams of becoming a junkie.” In the same way, spouses who decide to cheat are often already unfaithful in their internal trajectory. Great sins are often the product of many little decisions and are driven by internal rebellions that are finally offered opportunity. King Solomon might be the best example of all (see 1 Kings 10-11).

Acknowledging that our nature is fallen and susceptible to such compromise is a wise thing to do, especially when mixed with asking for God’s grace. One of Jesus’ last and most urgent commands to His disciples was for them to pray that they would not fall into temptation. The same request is a central part of how Christ taught all of His followers to pray in the Lord’s Prayer.

In other words, while not every sin may be expressly inevitable, each is possible. We are capable of it. To think otherwise is to sound an awfully lot like Peter, “Lord, I would never deny you.” Every fallen human being is at least capable of many evils, even the unthinkable ones.

If we are to accept our capacity to surprise even ourselves by the depth of our own depravity, we may need to deny ourselves things we’d like to have. Cutting off our limbs may mean some of us shouldn’t be in leadership, or shouldn’t travel as much as they do, or shouldn’t take that promotion, or accept that new job, or buy that new toy, or stay on Twitter.

Where the rubber of “there, but for the grace of God, go I” meets the road is in understanding the depth of our sinful capabilities and in bearing the responsibility of making arrangements to avoid it. There but for the grace of God go any of us. It’s true. We still have to grip that grace, from moment to moment, for dear life.
