The Good Life is a Sent Life
What missional theology teaches us about a flourishing life.
Missional theology has always confessed something strange about God: that God is a missionary God. We see this claim masterfully discussed in the seminal work of missiologist, David Bosch, in his book Transforming Mission. In other words, God the Father sends the Son. The Son sends the Spirit. The Spirit sends the church. The oldest name for this pattern is missio Dei, the mission of God, and its point is not that mission is one of the church’s programs but that sending runs all the way down into the life of God. Before the church has a mission, the church is one, because it belongs to a God whose love does not stay home.
If that is true of God, it should be true of the life God calls good. And yet the way we talk about the good life now suggests we have quietly stopped believing it.
The good life we have learned to want
Ask most people, religious or not, what a flourishing life looks like, and the answer arrives as an inventory. Health. Happiness. Meaning. Close relationships. Enough money to be unafraid. This is not a foolish list. It maps almost exactly onto what the best flourishing research measures, and the research is right that these are real goods that real lives need. The trouble is not the contents of the inventory but the grammar, which is the grammar of possession. Flourishing, in this telling, is something you accumulate and hold. It is a state you arrive at and, having arrived, defend.
A faith shaped by that grammar becomes a faith organized around acquisition. We come to church to be fed, to be filled, to be helped, to be resourced. None of that is wrong on its own, but notice what has happened to the direction of the whole enterprise. Everything points inward — to self. The blessing terminates in the blessed. And a God who is all sending has been enlisted in the service of people who mostly want to stay.
Blessed in order to be
The first blessing in the biblical story refuses this grammar outright. When God calls Abraham, the call is not “settle here and be well.” It is “go.”
Go from your country and your kindred and your father’s house.
The good life, at its origin, begins with departure. And the blessing that follows is more of a commission of sort: I will bless you, and you will be a blessing; in you all the families of the earth will be blessed (Genesis 12:3).
Notice that Abraham is blessed, fully and personally. And Abraham is blessed for something, toward someone, in order that nations he will never meet might be reached by a goodness that passed through his life on its way to theirs. Blessing, therefore, is not a reservoir. It is a current and one that is measured not by how much collects in Abraham but by how much moves through him.
This is the grammar the whole story keeps speaking. Biblical Israel is not chosen instead of the nations but on behalf of them, a light meant to be seen from far off. The prophets insist that a peace hoarded is a peace forfeited, that a people who keep their shalom to themselves have misunderstood what they were given. And when the pattern reaches its center, it takes the form of a person who is himself the Sent One, and who, on the far side of resurrection, gathers his friends only to turn them immediately outward: as the Father has sent me, so I send you (John 20:21). Even the gift of the Spirit at Pentecost is not a private warming. It is ignition. The room fills so the doors can open.
There is no point in this story where the good life is allowed to settle into mere having. Every time it tries, the story sends it somewhere.
What the science stumbled into
This is what, I think, should surprise us. When researchers set out, with no theological interest at all, to find what actually makes human lives go well, they keep arriving at the edge of this same claim.
The most reliable finding in the whole field of wellbeing is not that acquisition satisfies. Most psychological science studies point to what self-transcendence does. People who give, serve, mentor, and contribute report better wellbeing than people who merely consume, and the effect is not explained away by the fact that happier people give more. Giving appears to produce flourishing, not just accompany it. The developmental psychologists calls this generativity, which is a word used for the mature adult’s need to invest in something beyond the self, to pour into a next generation and a wider world. Its absence has a name too, and the name is stagnation, a self curved in on itself and slowly going stale. This is also referred to in the flourishing literature as languishing.
I have spent my research life on a related question, working with attachment theory, which studies the bonds that make us secure. Attachment science established something counterintuitive decades ago. A secure base is not for staying; it is actually for leaving. The whole function of a safe haven is to make exploration possible — so that one we confidently mature to seeing the attachment figure as their source of security. The securely attached child does not cling; the securely attached child ventures out, precisely because there is somewhere secure to venture from. Security that produces only more staying is not security working well. In attachment theory we call insecure anxious attachment, or what I like to call security malfunctioning.
Scripture says the blessed are blessed in order to be a blessing. The science says the healthy are made for more than health, that a good life kept turns stagnant and a good life given turns generative, that the whole tapestry of human security is built for sending. The good life, measured honestly, will not sit still.
The failure we mistake for faithfulness
Name the malfunction plainly, because we have learned to admire it. A Christianity organized around acquisition produces people and churches that are, by their own metrics, thriving, and by the deeper metric, stuck. The sanctuary becomes a bunker. Formation becomes a permanent readiness that never releases anyone; we disciple and study and prepare and prepare and are never quite sent. The endless preparation feels like seriousness. It is actually the good life curdling, security that has forgotten it was ever meant for exploration.
The opposite failure is real too, and it deserves a word so no one hears this as a summons to burn out. A sending that is not rooted is exploration without a base, and it collapses. The activist who never rests, the pastor deployed before being secured, the helper using the work to outrun an unhealed wound. These are not counterexamples to the argument. They are what happens when you try to send from a place that was never rooted. The point was never activity for its own sake. The point is that a rooted life is made to move, and a life that roots without ever moving has stopped halfway through its own design.
The good life leaves home, surely
So the good life is a sent life. Not because sending is a burden laid on top of flourishing, a tax levied on the well, but because sending is what flourishing is for. This reminds me of the story of Saul leaving his father’s home to look for missing donkeys — a sojourn that led him to the throne (1 Sam. 9). The blessing was always a current or a movement. The secure base was always for exploring. The God we confess was a sender before the world began, and the life that God calls good bears the family resemblance.
This does not mean that the ideals we measure in flourishing science are wrong. Health and happiness and meaning and love and stability are real goods, and I want them for you. Missional flourishing — this rooted and sent life that carries the googness of God outward for the good of others — changes what these ideals are for. They are not a reservoir to defend nor a means to an end. They are a base to send from. The question a flourishing life finally has to answer, in the final analysis of things, is what has moved through me on its way to someone else.
Abraham’s blessing began with a single word, and it is worth ending where the whole story starts. The word was not stay. The word was go.
