Tearing Down Babel
Legalism and the Wrecking Ball of Grace
In Genesis 11, we meet a group of people who look far more familiar to us than we might admit. Humanity has already moved from Eden to the flood and into a new world, yet the same restless impulse remains alive in the human heart.
Noah’s descendants gather in the land of Shinar, and with a mixture of ambition, insecurity, and pride, and decide to build a tower that will reach the heavens so they can make a name for themselves.
The story is ancient, but the instinct is not. We may not stack bricks or mix mortar, but we still build our own towers, attempting to secure an identity or a sense of nearness to God by what we do. Our towers just happen to be built out of works instead of clay.
Inward Legalism
The word legalism gets used so frequently that it often loses its sharpness. Sometimes we throw it around whenever obedience feels inconvenient, but Derek Thomas gives us a much more precise definition when he writes that legalism is the attempt to obey in order to earn God’s favor. It is the belief that by doing enough, or thinking rightly enough, or performing consistently enough, we can climb our way into God’s approval.
This is the instinct goes all the way back to Eden. Adam reached for fig leaves because he believed he could cover himself, and even now, we reach for our own versions of those leaves. We take the law, which was given for our good, and try to fashion it into something that will hide our shame and prove our worth. We end up sewing together robes of self-righteousness from the very commands that were meant to humble us, comfort us, and point us to Christ.
Outward Legalism
Legalism not only distorts our relationship with God; it distorts how we relate to the people around us. Dr. Thomas also observes that legalism shows up when we add rules or expectations that God Himself never gave. This is where the spirit of Babel comes through most clearly. The builders in Genesis believed that every brick placed was a step closer to heaven, and we often do the same thing, except the “bricks” we use are usually other people.
Legalism turns spiritual life into a ladder, and for a ladder to work, someone must be beneath you. The stricter the standard, the harsher the climate becomes, because once you commit to climbing your way to God, you must place someone lower in order to keep going higher. This is why legalistic environments often feel cold and indifferent. A heart that is focused on performance has little room left for mercy.
So, how do we dismantle the towers we build? Not by pretending they aren’t there and not by trying to build “better” ones. The answer is grace, the very grace we sing about so easily, even though its first work in our lives is often devastating. Grace does not politely rearrange our spiritual furniture; rather, it exposes the foundation. It forces us to confront the truth that we cannot climb to God, no matter how impressive our tower appears.
Grace is disruptive precisely because it destroys the illusion that we can earn anything from God. It shatters our pride and demolishes our self-assurance, leaving us with the only hope that truly saves. And while we often imagine grace as a one-time moment, the truth is that we need this wrecking ball again and again because we continually drift back toward building our lives on the shaky ground of our own efforts.
Rebuilding on Christ
If grace is the wrecking ball, the gospel is the reconstruction plan. The gospel does not simply tear down our self-made towers; it rebuilds our identity on a foundation that cannot be shaken. It continually reminds us that our acceptance before God rests entirely on Christ, on His righteousness, His obedience, His sacrifice, and His resurrection.
The gospel frees us from the exhausting work of self-salvation by telling us that we already have God’s favor in Christ. It pulls our eyes away from our performance and anchors us in the truth that Jesus is the One who came down when we could not climb up. The gospel clears away the debris of our Babel-like striving and replaces it with the steady, life-giving assurance that Christ has done everything necessary for our salvation.
So let’s be honest about the towers we tend to build and the fig leaves we still reach for. Let’s stop treating people as rungs on a ladder and stop using God’s law as material for self-exaltation, and let’s ask the Lord to keep bringing His grace like a wrecking ball to the structures we try so hard to erect.
