On belief, surrender, idols of effort, and keeping your lantern lit while the Master is away
When Jesus is asked by the crowd in John 6, “What must we do, to be doing the works of God?” the answer he gives is almost shockingly small. Not a list. Not a strategy. Not a ministry plan. Just this: “This is the work of God, that you believe in him whom he has sent.”
The work of God, in its most essential form, is trust. It is an orientation of the whole self — mind, will, affection — toward the one whom the Father has sent. And that answer has the power to quietly dismantle almost every assumption we carry about what it means to be a faithful, productive, useful Christian in the world.
“This is the work of God, that you believe in him whom he has sent.”
John 6:29
Tetelestai: The Work That Was Already Finished
The clearest window into what God’s work actually looks like comes not from a sermon but from a death. In John 19:30, as Jesus exhales his last breath on the cross, he says one word: tetelestai. It is finished. Paid in full. Completed, consummated, brought to its appointed end.
This is the same root word stamped across debt records in the ancient world — the mark a creditor made when an account was settled. Jesus was not announcing defeat. He was issuing a receipt. The covenant God made with Abraham, the law given through Moses, the sacrificial system, the longing of the prophets — all of it, gathered into this single moment, resolved.
If tetelestai is the foundation, then anything we call “God’s work” must begin there. Not with our effort added on top of an incomplete transaction. Not with our striving to close a gap that still exists. The gap is closed. The debt is canceled. God’s work, in the deepest sense, is already done — and we are invited to live inside that reality, not labor toward it.
When Our Work Becomes Worldly
Here is the slow drift that happens in so many faithful lives: we begin in belief, and somewhere along the way we quietly shift into performance. The call to bear witness becomes a project to manage. The invitation to love our neighbors becomes an obligation to optimize. The simple command to make disciples of all nations becomes an identity — something we are known for, something we protect, something we can lose.
Works become worldly not necessarily when they are done in the world, but when they are no longer anchored in the finished work. When the doing outruns the believing. When we are more anxious about output than about the one in whose name we work.
There are two particular ways this manifests, and they are worth naming plainly.
The first is when earthly responsibility becomes the whole horizon — when the work of feeding the hungry, seeking justice, building the church, raising children well, or serving the poor quietly displaces the vertical relationship from which all of it is meant to flow. These are not bad things. They are profoundly good things. But when they become the primary source of meaning, the daily report card by which we measure whether God is pleased with us today, they have crossed over from vocation into idol. We have begun to believe not in the one who was sent, but in our own sending.
The second is when the work becomes identity — when being a disciple-maker, a pastor, a servant leader, a missionary becomes so fused with the self that it can no longer be set down. This is the person who cannot rest without guilt, who reads Sabbath as laziness, who has slowly replaced “I am a child of God” with “I am a person who does significant things for God.” The distinction sounds subtle. It is not. One is a position received. The other is a performance maintained.
The work was never meant to be your identity. It was meant to be the overflow of one.
The Great Commission Is an Instruction, Not an Identity
The Great Commission in Matthew 28 is breathtaking in its scope and its simplicity. Go. Make disciples. Baptize. Teach. And I am with you always. It is given to people who have already seen the risen Christ, who are already standing in the grace of the resurrection. It is not the mechanism by which they become acceptable — it is the natural spillover of people who have been undone by the news that death has been defeated.
The commission is an instruction. When we make it an identity, we subtly place it before the one who gave it. We become defined by the going rather than by the one who sends. And ironically, when the commission becomes an identity rather than a response, it often becomes harder to actually do — because now the stakes are our selfhood, not just our faithfulness.
The same is true of the covenant. God’s original covenant with Abraham was not fundamentally about Abraham’s performance. It was about God’s promise. I will be your God, and you will be my people. Jesus, as Paul argues relentlessly in Galatians and Romans, is both the fulfillment of that covenant and the one in whom we are included in it — not by our works, but by faith. To do God’s work is to inhabit that covenant, not to replicate it through effort. To trust that the same God who kept his promise to Abraham, who raised Jesus from the dead, who breathed the Spirit into the church at Pentecost, is the one holding your life together right now.
The Parable of the Lit Lanterns
In Luke 12, Jesus tells a parable that upends the usual logic of waiting. A master has gone away to a wedding banquet. He will return — but the hour is unknown. And the question Jesus puts to his servants is not: How much can you accomplish before he gets back? The question is simply: Will your lamps still be burning when he comes through the door?
“Be dressed for service and keep your lamps burning, like servants waiting for their master to return from a wedding banquet — so that when he comes and knocks, they can immediately open the door for him.”
Luke 12:35–36
The lamp is not a metaphor for productivity. It is a metaphor for readiness — for a self that is oriented toward the master’s return, alive to his presence, not sedated by distraction or hollow busyness. The servants who are blessed are not praised for what they built in his absence. They are praised for remaining awake, for keeping the flame.
What feeds that flame? Belief. Worship. Scripture absorbed slowly. Prayer that doesn’t feel like reporting. Community where people know your actual name. Confession and forgiveness practiced as a regular sacrament, not a crisis intervention. These are not the impressive works — no one posts about them. But they are what keeps the oil in the lamp.
Living It Now — Not Waiting for Him to Return
One of the stranger failures of contemporary Christian imagination is the idea that the fullness of life in Christ is essentially deferred — that what Jesus came to establish is fundamentally a future arrangement, and that our job is to endure the present until that arrives. This is not what Jesus announced. He announced the kingdom of God as something that had broken into the present. The kingdom of heaven is at hand. The time is fulfilled. Not: the time is coming. Fulfilled.
The community Christ intended — people who forgive as they have been forgiven, who bear one another’s burdens, who share what they have with those who have nothing, who welcome the stranger, who speak the truth in love, who grieve together and celebrate together — this is not the preview of heaven. This is the presence of heaven in the world now. This is the covenant community, the body through which the risen Christ continues to act.
To do God’s work is to actually live this, today. Not to prepare for it. Not to attend programs about it. Not to post thoughtfully about the importance of it. But to arrive at someone’s door with food when they are too broken to cook. To stay in the hard conversation instead of the comfortable silence. To practice generosity in amounts that feel genuinely costly. To worship as though the resurrection actually happened last week.
The lamp is lit by believing. It stays lit by being in community. It is carried into the world by love that does not count the cost, because the one who paid the ultimate cost already said: it is finished.
Tetelestai.
It is finished — now live it.
