Martyn Lloyd-Jones has said, “The main heresy is still justification by works.” At first glance, it sounds like something aimed at legalistic religion or outdated theological debates. But Lloyd-Jones is not merely critiquing a doctrine “out there” he is diagnosing something “in here.”
Because justification by works is not just a historical heresy—it is the default instinct of the human heart.
The Reflex We Practice
We do not need to be taught to think in terms of performance and acceptance.
It naturally shows up when we think like this:
I had a good week spiritually, so God must be pleased with me.
I failed again, so I should probably stay away from God for a while.
If I try harder, maybe I’ll feel closer to Him.
Even when we affirm justification by faith with our lips, we quietly live as though our standing before God rises and falls with our performance.
Scripture shows us where this reflex begins. In Genesis 3, after Adam and Eve sin, their first response is not repentance but covering. “And they sewed fig leaves together and made themselves loincloths” (Gen. 3:7). Before God speaks a word, they are already trying to deal with their shame through their own effort.
Sin does not merely make us guilty; it distorts how we relate to God. Instead of running to him, we begin managing our image before him. We move from trust to performance.
From Fig Leaves to Spiritual Performance
We may not sew fig leaves, but we have more sophisticated versions.
We measure ourselves by spiritual disciplines, ministry involvement, moral consistency, or even theological clarity. These are good things in themselves, but when they become the basis of our confidence before God, they turn into fig leaves.
The problem is not obedience. The problem is why we obey. When obedience becomes a way to secure acceptance, it is no longer the fruit of grace; it becomes a substitute for grace.
This is why justification by works is so persistent. It does not always appear as crude legalism. Often, it hides beneath sincere devotion.
We read our Bibles, but subtly to reassure ourselves that we are “doing okay.”
We serve, but with an undercurrent of needing to feel valuable.
We repent, but with the hope that our repentance itself will restore our standing.
In all of this, we are still trying to justify ourselves.
The Gospel Reversal
Into this deep-rooted instinct, the gospel speaks a radically different word.
Paul writes, “For we hold that one is justified by faith apart from works of the law” (Rom. 3:28). Again, in Galatians, he states, “a person is not justified by works of the law but through faith in Jesus Christ” (Gal. 2:16).
This is not merely a doctrinal correction; it is a complete reversal of how we think. It is what makes Christianity utterly unique. Every other system, religious or secular, ultimately operates on a performance framework. Do enough, be enough, prove enough, and then you will be secure.
The gospel dismantles that logic at its root. Our acceptance before God is not based on what we do, but on what Christ has done. “It is finished” (John 19:30) is not just a statement about the cross, but it is a declaration about our standing.
Nothing needs to be added, and nothing can be added.
Why We Keep Returning to Works
If this is true, why do we keep drifting back? Because justification by works feels controllable. Grace, on the other hand, requires surrender.
To live by works is to remain in charge: I can measure, improve, compare, and evaluate myself. But to live by grace is to admit that I bring nothing. It is to rest entirely on another.
That kind of dependence is deeply uncomfortable for the human heart.
This is why Paul confronts the Galatians so sharply: “Having begun by the Spirit, are you now being perfected by the flesh?” (Gal. 3:3). They had received the gospel, but they were slowly reconstructing a system of self-justification.
And we do the same. We begin with grace, but we move on to effort (Gal. 1:6). We trust Christ for salvation, but we trust ourselves for growth. We believe the cross forgives us, but we live as though our daily performance sustains us.
In doing so, we subtly shift the centre from Christ’s finished work to our ongoing work.
Living from Acceptance, Not for It
The Christian life is not about moving toward acceptance, it is about living from it.
When we know we are already accepted in Christ, obedience becomes a response, not pressure (Gal. 5:1). Repentance becomes return, not punishment (Isa. 30:15). Spiritual disciplines become means of communion, not measures of worth (2 Pet. 1:5-8).
We are free to be honest about our sin because our standing is not at stake. We are free to pursue holiness because it is no longer driven by fear.
This is what Jesus invites us into: “Come to me, all who labour and are heavy laden, and I will give you rest” (Matt. 11:28). The burden is not just sin; it is the exhausting effort to justify ourselves. Rest begins when that effort ends.
A Daily Return to Grace
Justification by faith is not only the entry point of the Christian life—it is the foundation of the entire journey (Rom. 5:1-2). This is not a lesson we graduate from.
We return to it daily. When we fail, we remind ourselves: Christ is enough. When we succeed, we remind ourselves: Christ is enough. When we feel distant, we remind ourselves: Christ is enough. This is how the heart is slowly retrained.
The instinct to justify ourselves does not disappear overnight. But as we repeatedly come back to the gospel, something shifts. The grip of performance loosens, and the freedom of grace deepens (Eph. 2:8-9).
And over time, we begin to live, not as people trying to earn acceptance, but as people who have already received it.
The End of Self-Justification
Lloyd-Jones was right. The main heresy is still justification by works, not only in doctrine, but in disposition.
But the gospel remains just as powerful. It meets us in our striving, exposes our fig leaves, and invites us into rest. It tells us that our standing before God is secure, not because of what we have done, but because of what Christ has accomplished (2 Cor. 5:21).
And in that place, something remarkable happens. We stop trying to become acceptable and begin to live in freedom.
