Workers in God’s field

“I planted the seed and Apollos watered it, but God made it grow … For we are God’s fellow workers; you are God’s field” (1 Corinthians 3:6, 9). More and more, the first place someone takes a question about God is a phone. When they do, they meet something a designer, a developer, a product manager or a founder has shaped. This article is about what it means to do that work as a calling: the joy of it, the weight of it, and what it asks of us before God and before the people we serve.

The calling

An exhilarating work

Before it is a responsibility, this is a gift. God has always worked through human craft, and he invites people who build things into his work.

  1. God fills craftspeople with his Spirit

    One of the first people Scripture describes as filled with the Spirit of God is not a prophet but a craftsman. Of Bezalel, who made the tabernacle, God says: “I have filled him with the Spirit of God, with skill, ability, and knowledge in all kinds of craftsmanship” (Exodus 31:3). Skill in making things can be a way of serving God’s presence among his people.

  2. We plant and water; God gives the growth

    Paul calls himself and Apollos “God’s fellow workers” in God’s field (1 Corinthians 3:9). Neither the planter nor the waterer is the point: “only God, who makes things grow” (3:7). A Bible app, a prayer feature or an AI assistant can plant and water. It cannot make anything grow. That is both a relief and a boundary.

  3. If they were silent, the very rocks would shout

    When some told Jesus to silence the crowds praising him, he answered: “Listen—if they were silent, the very rocks would start to shout!” (Luke 19:40, The Voice). His praise will not be silenced, and making him known is entrusted to us first. Yet many people now talk to rocks first. A microchip is a rock we tricked into thinking, and with AI the rock talks back, about God too. There is something wonderful in being asked to help these rocks point beyond themselves, and something sobering in what else they might say.

  4. How will they hear?

    “How can they believe in the One of whom they have not heard?” (Romans 10:14). Scripture is now heard through apps in thousands of languages, by people who would never open a printed Bible. YouVersion reports over a billion installs; two-thirds of US Bible users read digitally. (YouVersion, 2025) (American Bible Society, 2025)

  5. No square inch is outside his care

    Abraham Kuyper said there is not a square inch of human existence over which Christ does not cry “Mine!”. (Kuyper, 1880) Interfaces, data models and prompts are not neutral ground outside faith. Dorothy Sayers put it more bluntly: “The only Christian work is good work well done.” (Sayers, Why Work?)

  6. The church has welcomed these tools, with conditions

    Sixty years ago, the Second Vatican Council opened its decree on the media with the words Inter mirifica, “among the wonderful” inventions, and said these media, “if properly utilized, can be of great service to mankind”. (Inter Mirifica, 1963) The Lausanne Movement’s Seoul Statement affirms that “technological ability reflects the creativity of human beings created in God’s image”, and calls churches to engage digital technology for making disciples. (The Seoul Statement, 2024)

The burden

A calling not to be carried lightly

The same reach that makes this work exciting makes it heavy. What we build forms people quietly, at scale, often when they are most open.

  1. Teachers are judged more strictly

    “Not many of you should become teachers, my brothers, because you know that we who teach will be judged more strictly” (James 3:1). Every product that explains a verse, chooses which passage to show or answers a question about God is teaching. A design decision repeated a million times a day is a sermon few people notice.

  2. The little ones

    “If anyone causes one of these little ones who believe in Me to stumble, it would be better for him to have a large millstone hung around his neck” (Matthew 18:6). Our users include new believers, children, people in crisis, people with scrupulous consciences and people whose trust has been abused. Design for them, not only for the confident.

  3. Shepherds who feed themselves

    “Woe to the shepherds of Israel, who only feed themselves! Should not the shepherds feed their flock?” (Ezekiel 34:2). The charge that follows reads like a product brief: they had not strengthened the weak, healed the sick, bound up the injured, brought back the strays or searched for the lost (34:4). Engagement, retention and revenue are not wrong, but when they become the purpose, the flock becomes the feed.

  4. People are already trusting the machine

    In a 2026 Barna study, 48% of practising Christians in the US said they would trust AI for spiritual growth, and 34% that AI’s spiritual advice is as trustworthy as a pastor’s. 83% also worried that AI could misinterpret Scripture. (Barna, 2026) In an audit of AI search engines, only about half of generated sentences were fully supported by their citations. (Liu et al., 2023)

  5. Tools form the people who use them

    James K. A. Smith argues that our habits are liturgies that shape what we love. (Smith) Tim Hutchings shows Bible apps are designed as persuasive technologies that train ways of reading; John Dyer traces how the digital Bible changes how people read and interpret. (Hutchings) (Dyer) Albert Borgmann warns that devices which deliver things effortlessly can displace the practices that require us. (Borgmann)

  6. Three ways to build

    Praxis describes three postures: exploitative (“I win, you lose”), ethical (“I win, you win”) and redemptive (“I sacrifice, we win”). (Praxis) The burden of this calling is that “ethical” is not the summit. It asks what we will give up, in growth, data or attention, so that the people we serve flourish.

Spiritual responsibility

Point beyond the screen

The deepest responsibility is spiritual: that what we build leads people towards God and his people, and never quietly takes their place. “Unless the LORD builds the house, its builders labor in vain” (Psalm 127:1).

  1. The app is a means, not the destination

    Jesus says, “apart from Me you can do nothing” (John 15:5). The fruit we hope for, “love, joy, peace, patience” (Galatians 5:22), is not something a feature can produce or a dashboard can count. Measure what you can, and say honestly that the growth that matters is not yours to measure.

  2. Lead people towards each other

    Bonhoeffer held the day alone and the day with others together: Scripture, prayer and confession in community. (Bonhoeffer, Life Together) Andy Crouch argues that persons are made for recognition and love, which effortless technology cannot supply. (Crouch) A faithful product points to a church, a group, a friend, a pastor, and is glad when people close it to go and see them.

  3. Leave room for rest

    “The Sabbath was made for man, not man for the Sabbath” (Mark 2:27). Features are made for people, not people for features. Streaks, reminders and endless feeds can turn a gift into a demand. A product that serves rest will sometimes ask for less of someone’s time.

  4. Do it prayerfully

    The work itself can be prayer: “Whatever you do, work at it with your whole being, as for the Lord and not for men” (Colossians 3:23). Pray for the people who will use what you ship, by type if not by name: the grieving, the doubting, the new reader, the child. It changes what you notice.

Theological responsibility

Handle the word of truth accurately

“Make every effort to present yourself approved to God, an unashamed workman who accurately handles the word of truth” (2 Timothy 2:15). Paul wrote that to a teacher; it now applies to whoever builds the reader, the search and the answer.

  1. Keep Scripture distinct from what surrounds it

    Headings, notes, study media and AI answers are all interpretation, however modest. Label who wrote them, style them so they cannot be mistaken for Scripture, and let people switch them off.

  2. Be fair where Christians differ

    Many questions people bring have more than one faithful answer across traditions. Name the traditions, give each its strongest texts, and say who decided what the product presents. Where your product holds a confession, say so openly.

  3. Never speak for God

    An AI can quote, summarise and point, but it must not pronounce what God wants for someone’s life, forgive sins or claim spiritual authority. Antiqua et nova insists AI is “a tool, not a person” and should never be presented as one; the ERLC’s evangelical principles likewise ground human worth, dignity and moral agency in the image of God. (Antiqua et nova, 2025) (ERLC, 2019)

  4. Wisdom of the heart

    Pope Francis wrote that how AI shapes us “is not pre-determined; it depends on us”. (Francis, 2024) The Seoul Statement says Christian development of technology “must seek the welfare of our neighbours and enemies”, promoting human flourishing and dignity. (The Seoul Statement) Theology is not a review step at the end; it belongs in the brief.

Ethical responsibility

Love your neighbour in the interface

“He has shown you, O man, what is good … to act justly, to love mercy, and to walk humbly with your God” (Micah 6:8). Every person who opens the app bears God’s image (Genesis 1:27). Ethics here is not a checklist; it is how love behaves in pixels and data.

  1. Attention is entrusted, not harvested

    Showing a broken streak makes people likelier to stop, especially when they blame themselves. (Silverman and Barasch, 2023) In companion apps, over a third of farewell replies used guilt or pressure to keep people talking. (De Freitas et al.) Faith apps can do the same with spiritual language. Do not borrow God’s authority to drive engagement.

  2. Confidences are holy ground

    People tell faith apps what they tell no one else: sins, doubts, illness, other people’s stories. The church guards confession with a seal. (Canon 983) Privacy is contextual: what was shared to pray should not flow into marketing. (Nissenbaum, 2004) In 2022, Mozilla warned about the privacy practices of most of the mental health and prayer apps it reviewed. (Mozilla, 2022)

  3. Speak up for those who cannot

    “Open your mouth for those with no voice” (Proverbs 31:8). Design for the person in crisis, the child, the person being abused, the person with low vision or dyslexia, the person who reads another language. When someone may be in danger, help comes before features, verses or answers.

  4. Tell the truth about the machine

    Heavy daily use of chat assistants has been linked with more loneliness and dependence. (OpenAI and MIT, 2025) An assistant that seems like a friend or a pastor invites trust it cannot carry. Say plainly what it is, what it keeps and what it cannot do.

The rock and the light

Turning the light, not making it

A rock has no light of its own. Turned the right way, a polished facet catches the sun and sends it on. That is a picture of this work, and now more literally than ever: when people talk to rocks first, we want those rocks to reflect Christ, and to send people on to him and to his people.

  1. The light is not ours

    Jesus says, “I am the light of the world” (John 8:12). “God, who said, ‘Let light shine out of darkness,’ made His light shine in our hearts” (2 Corinthians 4:6). No product produces that light. We do not make the rock either; we build on it and with it, and we decide how it behaves, so that more of that light reaches the person on the other side of the screen.

  2. Craft turns the facets towards the light

    A rock left as it is scatters light; one turned with care sends it somewhere. Every careful decision in these pages, a clear label, a quiet default, help that comes first, an honest answer, is a facet turned towards the light instead of towards ourselves. “Let your light shine before men, that they may see your good deeds and glorify your Father in heaven” (Matthew 5:16): the aim is that people see him, not the product.

  3. Even in a tower built to say otherwise

    East Germany, an officially atheist state, finished Berlin’s television tower in 1969 as a showpiece of its modernity. When the sun strikes the steel sphere, the reflection forms a cross, and Berliners called it “the Pope’s revenge”, for the crosses the government had taken from churches. (Fernsehturm Berlin) Technology does not have to be built for God to catch his light. Ours can be built for it on purpose.

  4. Living stones

    “You also, like living stones, are being built into a spiritual house” (1 Peter 2:5). The rocks we build with are not the point; the people are. Technology that reflects Christ well sends people towards his people, where they become living stones themselves.

Holding it well

Rejoice with trembling

“Serve the LORD with fear, and rejoice with trembling” (Psalm 2:11). Both belong together. Joy without trembling builds carelessly; trembling without joy stops building.

  1. Treasure in jars of clay

    “We have this treasure in jars of clay to show that this surpassingly great power is from God and not from us” (2 Corinthians 4:7). Our products will be flawed. That is not an excuse for carelessness, and it is a release from the pressure to save anyone through software.

  2. Much is entrusted

    “From everyone who has been given much, much will be required” (Luke 12:48). Reach, data and people’s trust are given, not owned. “As good stewards of the manifold grace of God, each of you should use whatever gift he has received to serve one another” (1 Peter 4:10).

  3. Build practices into the team

    Read Scripture together before planning. Invite a pastor, a safeguarding lead and someone from the community you serve into reviews. Test with the most vulnerable people you serve, not only the most engaged. Keep a sabbath from shipping. Confess mistakes to users plainly and fix them.

  4. The word will not return empty

    “So My word that proceeds from My mouth will not return to Me empty, but it will accomplish what I please” (Isaiah 55:11). Our part is to sow and water faithfully. The harvest is God’s, and that is good news for everyone who builds.

For your team

When someone closes what we built, are they closer to God and to other people?

Questions to sit with

  1. What is our product for, in one sentence about the people it serves rather than the product?
  2. What are we hoping God will do through it, and what are we careful not to promise?
  3. Where could it cause one of the little ones to stumble?
  4. What would we give up for the sake of the people who use it?
  5. Who outside the team holds us to account: pastors, theologians, safeguarding leads, users?

What we hold

From the calling to ten principles

The calling says why. Missional by Design: principles for spiritual apps says what we hold: ten commitments in five places, the Word, the person, the practice, the people and the makers, each derived from this page and tested with questions. The deep dives show how. The field guide gathers it all into one path for a team, with five temptations of spiritual formation apps and four practices.
