A Sermon for Bloomsbury Central Baptist Church
Sunday 20 September 2026


Genesis 12.1-9; Matthew 28.19-20

If you've ever moved house,
            you'll know that the first question anybody asks isn't why.
It's where. Where are you going?
            And you tell them, and they nod, and they either say "oh, lovely"
            or they say "oh" in a slightly different tone,
and either way the conversation can proceed,
            because a place has been named
            and the world has been made manageable again.

Abram couldn't answer the question.

God gives him what sounds, at first, like a fairly comprehensive brief.
            Leave. Travel. Become a nation.
            Be blessed. Be a blessing.

There's a promise of descendants,
            a promise of reputation, a promise of protection.

It's generous, it's expansive, and it's missing precisely one detail,
            which is the only detail anybody ever actually wants.

Go from your country and your kindred and your father's house
            to the land that I will show you.

Not the land I'm showing you now.
            Not the land you can find on a map, with a postcode and a train line
            and a school five minutes' walk away.
The land that I will show you.
            Future tense. Later. Trust me.

We've just sung about this
            — "God it was who said to Abraham, pack your bags and travel on" —
and I love that hymn,
            but it does make it sound rather brisker than it was.

Because look at the order of the leaving.
            Country, then kindred, then father's house.
It narrows. It zooms in.
            Each phrase costs more than the one before it.

Your country is, in the end, an abstraction
            — a flag, a set of customs, a way of pronouncing things.
Your kindred are the people who know your business.

But your father's house is the roof and the table
            and the smell of the place
            and every single person who has ever known what you were like as a child.

Genesis takes its time getting to the painful bit.
            It knows what it's asking.

And Abram is seventy-five years old.

We moved to London fourteen years ago,
            and when agreed to come to Bloomsbury, we didn’t have a postcode either,
            because the church had yet to buy the manse for us to live in.

We just had a letter of appointment, a church meeting decision,
            and a trust that something suitable would be found in time; and it was.

Abram just had a voice and a promise and a direction of travel. That's it.
            Whatever faith is, it isn't certainty.

Faith is what you do when you've run out of certainty and you go anyway.

Now, before we get too misty-eyed about the father of faith, notice verse 5.
            Abram took his wife Sarai.
She doesn't get a call. Nobody speaks to her.
            She appears in the sentence somewhere between the nephew and the livestock,
            in a list of things that were taken.

And a few verses further on — just past where our reading stops —
            when the famine comes and Abram gets frightened,
he saves his own skin by passing her off as his sister
            and letting her be taken into Pharaoh's household.
It's a squalid little episode and Genesis doesn't soften it.

I mention it because we should be clear-eyed about who God calls.
            Abram is not a moral hero.
He is frightened, he is calculating,
            and when it comes to it he is prepared to trade his wife for his safety.

And God keeps going with him anyway.
            Which is, if we're honest, more of a relief than an embarrassment.
God's call has never waited for us to become admirable first.

But here's the thing we tend to walk straight past.
            What God asks Abram to do is become a migrant.

That's the founding act of the people of God.
            Not a battle, not a coronation, not the building of a temple.
A man packing up a household
            and setting out for somewhere he can't name
            because he believes he's been spoken to.

The whole story starts with someone crossing a border
            without a plan he could articulate to an official.

Put Abram in the present tense and think about what happens to him.
            He arrives somewhere he has no papers for.
He can't produce documentation for the promise.
            He has no permission to be there, no permanent address,
                        no recourse to public funds.
He'd be a case number and then a headline.
            He would meet the full apparatus
                        of what we learned to call the hostile environment,
            and he would find that the country he'd arrived in
                        had developed an entire vocabulary
                        — floods, swarms, waves, queues being jumped —
            designed to make it easier not to look him in the face.

I'm not making a party political point. I'm making a Genesis point.
            The Bible's founding family are economic migrants,
            then famine refugees, then resident aliens, then slaves,
and the law that emerges from all that
            keeps hammering the same instruction:
you shall love the stranger, for you were strangers.
            We didn't get that from nowhere.
            We got it because it's who we are.

And look around this room.

This is a city-centre church on Shaftesbury Avenue.
            Many of us are here because at some point we,
                        or our parents, or our grandparents,
            left a country and a kindred and a father's house
                        and came to a place we'd been told about but hadn't seen.
We are not reading somebody else's story this morning.

Then Abram arrives, and Genesis 12.6 does something remarkable.
            He reaches Shechem, he stands at the oak of Moreh,
and the narrator adds — almost as an aside, almost under his breath —
            at that time the Canaanites were in the land.

The promised land has people in it. It always did.
            Genesis knows this perfectly well and says so out loud,
                        in the very same paragraph as the promise,
            and then leaves the sentence sitting there like an unexploded shell
                        for the next four thousand years.

Because the most dangerous thing you can do with Genesis 12
            is read it as a title deed.

It has been read that way, of course.
            It was read that way by Christian crusaders.

It was read that way by the Puritans who sailed for New England
            convinced they were entering an inheritance prepared for them,
                        and who worked out a careful argument
            that land the people already living there hadn't fenced or ploughed
                        was land nobody owned.

It was read that way in South Africa,
            where a whole theology of chosen people and promised land was constructed,
            and where apartheid was the result,
                        a theology the Dutch Reformed Church
                        has since had the grace to confess, publicly, as sin.

And it is being read that way now, in the hills of the West Bank,
            where Genesis is quoted as a property document
while families who have farmed olives for generations are moved off,
            and where Palestinian Christians — my friend Munther Isaac among them —
have to preach every Advent under the weight of a promise
            that has been turned into a weapon aimed at them.

So let's be careful, and let's be specific
            about what Abram actually does with the promise.

He never owns a square foot of it.
            He pitches a tent.
            He builds an altar and moves on.

He builds a second altar and moves on again.

He journeys by stages towards the Negeb, and he keeps journeying,
            and the only piece of that land he ever legally acquires in his whole life
            is a cave to bury Sarah in.
That's it. The father of the promise dies a resident alien with a grave.

In Abram's hands the promise is a vocation, not an entitlement.
            He walks it, he worships in it, he blesses in it.
He does not seize it.
            And any reading of Genesis 12 that arrives at bulldozers
            has gone wrong somewhere well before the bulldozers.

Because the promise has a purpose clause, and it's the last line,
            and it's the whole point.
In you all the families of the earth shall be blessed.

Everything before that is instrumental.
            The nation, the name, the descendants numerous as the dust
            — none of it is the destination.

It's plumbing.
            It's the pipework by which blessing travels from God to everybody.
A chosen people is not a favoured people.
            A chosen people is a people chosen for something,
            and the something is always everybody else.

Blessing that stops with the blessed isn't blessing. It's hoarding.
            And a church that receives grace and then builds a wall round it
                        hasn't misunderstood a detail;
            it's misunderstood the sentence.

Which is why the lectionary puts Matthew 28 next to it,
            and it's the right call, because it's the same sentence continued.

All the families of the earth becomes all nations.
            Abram's commission and the Great Commission
            are one promise reaching its terms.

But we have to be equally honest about what's been done with this text.
            "Go and make disciples of all nations"
            has been carried up beaches ahead of soldiers.

It has been used to justify taking children from their parents
            and languages out of their mouths.

Go and make disciples has been heard, over and over,
            as go and make subjects,
            go and make Europeans,
            go and make them like us.

The Church has an enormous amount to be sorry for here,
            and saying so isn't disloyalty;
it's the minimum honesty required before we're allowed to read the verse at all.

So let’s try to read it properly.

Make disciples, Jesus says — learners, apprentices, people who follow.
            Not converts, not subjects, not statistics.

And then: teaching them to obey everything I have commanded you.
            Well — what did he command?
Go back through Matthew and find out.
            Love your enemies. Pray for those who persecute you.
            Turn the other cheek. Forgive seventy-seven times.
Whoever wants to be first must be last.
            Blessed are the peacemakers, the meek, the merciful.

You cannot make disciples of that at gunpoint.
            The content of the commission rules out the methods.
If the message is enemy-love,
            then any mission conducted by coercion
            has already failed before it's opened its mouth.

And notice who's standing on that mountain in Galilee.
            Verse 17, just before our reading: they worshipped him, but some doubted.

The commission is handed over to a committee
            that can't even agree whether it's actually him.
Nobody is asked to resolve their doubts first.
            Nobody is screened out.
That's the apostolic succession, and frankly that's us.

Then the last line, which is the line that holds the whole thing up.
            I am with you always, to the end of the age.

Not "go, and send me a report."
            But with you. Alongside.

And the one who says it is the one whose hands are still marked,
            who has already been on the receiving end
            of every kind of power we might be tempted to use.

Which means we don't carry Christ to anywhere.
            He's already there.

He got there first, he's been at work in every place we think we're bringing him to,
            and the honest description of mission is not delivery but arrival,
turning up somewhere
            and slowly realising that the Spirit has been busy here
            for generations without waiting for our permission.

The end of the age isn't a deadline we're racing towards.
            It's the horizon we already live under.

So Abram builds his altars in a land that isn't his,
            among people who were there first,
in the long meantime between the promise
            and anything visibly happening.

He gets no fulfilment.
            He gets a tent, a route, an altar, and a grave.
            And he worships anyway.

That is a picture of the people of God,
            and it is a more comforting one than it sounds,
because most of the Christian life is lived in that meantime,
            after the promise, before the evidence,
with the removal van already loaded
            and no sign yet of the land you were told about.

Worship, in that gap, isn't consolation. It's practice.
            It's how hope gets rehearsed until it becomes a habit.

And it means the question this text puts to us this morning
            isn't are we prepared to move to Shechem.

It's this: what's the country, the kindred,
            the father's house we're being asked to leave?

Because it usually isn't geography.
            It's the familiar. It's the way we've always done it.
It's the assumption that the shape of church we inherited
            is the shape God requires.

Provoking faith in the heart of London is a fine thing to say,
            and none of us can tell you exactly where it leads,
            which is more or less the point.

Just before the sermon we sang "Will you come and follow me",
            and I'd ask you to notice that it's verse after verse of questions

            before anybody dares an answer.
That's not a defect in the hymn.
            That's the most accurate thing we'll sing today.

In a moment we’ll sing "Forth in the peace of Christ we go,"
            and then finish with a hymn about a hand
            that has guided the flock from age to age.
A hand. Not a map.
            God has never yet given anybody a map.

And then those doors open onto Shaftesbury Avenue,
            one of the most crowded and most anonymous streets in Europe,
where all the families of the earth walk past each other
            at one o'clock on a Sunday afternoon,
            not knowing a single name.

There is no postcode this morning either.
            There is a voice, a promise, and a pavement.

You were blessed to be a blessing.
            It was never for you alone.
It starts outside that door.

Amen.
