Will we respond to the watchman's call?

Share 

When danger looms, the speed and clarity of the warning can make all the difference. And in London today, the gospel is that urgent message of hope, shares Graham Miller, LCM Chief Executive.

In 1588, when the Spanish Armada threatened England’s shores, the safety of the nation depended on how quickly the warning could spread.

Across the hills, wooden beacons stood ready. When danger was spotted on the horizon, the first flame was lit – then another, and another – until the whole country was roused and prepared.

The cascade of fire swept across the land, calling people to action.

This image of urgent warning is echoed in Ezekiel 33, where God appoints a watchman on the wall. When danger approaches, the watchman must sound the trumpet. If he stays silent, the consequences are devastating. But if he speaks, lives may be saved.

This ancient picture speaks powerfully into our present reality. London is not facing invading ships, but it is facing something far more serious: the holy judgment of God.

And into this moment, God is calling His people to be watchful, faithful, and courageous – to carry a message of hope and truth to those who have yet to hear it.

The responsibility is real, but it is not ours to bear alone. We are not called to produce results, but to be obedient. The outcome is in God’s hands.

Our task is to speak – to share the good news of Jesus Christ with clarity and compassion, trusting that the Holy Spirit will do the work of transformation.

FAITHFUL WITNESS, NOT FEARFUL SILENCE

There are moments when this calling feels daunting. It’s easier to stay quiet, to avoid difficult conversations, to soften the message so it feels more palatable.

But the gospel is good news precisely because it confronts the reality of our need – and offers the grace of salvation.

To withhold that message is not kindness; it is silence in the face of suffering.

Imagine a doctor who sees a patient with a serious infection but chooses not to speak up. That doctor would be failing in their duty.

In the same way, we are surrounded by people who are spiritually unwell – people who may never hear the hope of the gospel unless someone speaks. We are not called to diagnose and walk away. We are called to offer life.

God is calling his people to be watchful, faithful, and courageous—to carry a message of hope and truth.

A MOVEMENT OF MISSION ALREADY IGNITED

Thankfully, we are not alone in this. The trumpet blast of the watchman was never meant to be a solitary note. It was meant to spark a movement – a cascade of beacons, a fire of witness spreading from church to church, borough to borough.

At Pentecost, tongues of fire rested on the apostles, and the gospel spread from Jerusalem to Judea, to Samaria, and to the ends of the earth.

That same fire is burning today. The same Spirit is equipping us now.

London is a city of influence, diversity, and spiritual need. And God is at work.

We are seeing signs of renewal – in diaspora communities, in poorer neighbourhoods, among young people who are praying and sharing faith with boldness. The fire is spreading peer-to-peer, heart-to-heart.

Yes, I believe we are seeing a Quiet Revival in London (which you can hear more about at lcm.org.uk/revival). This is not the work of one preacher or one organisation. It is a movement. And it is growing.

At London City Mission, we believe God is igniting a movement of mission in the local church. We are seeing churches catch the vision – not just for outreach programmes, but for whole-life witness.

Leaders and congregations are stepping into their calling as beacons of light in their communities, sharing the gospel with those who might never walk through a church door.

Let’s light the beacons together. Let’s carry the flame of the gospel into every corner of this city. Let’s be faithful watchmen.

THE TIME IS NOW

The need is urgent. But the opportunity is extraordinary. Whether you feel confident or unsure, strong or weak, God delights in using ordinary people for His extraordinary purposes.

He used Jonah. He used Peter. He can use us. It could start with a simple prayer and a hello to a neighbour.

Let’s light the beacons together. Let’s carry the flame of the gospel into every corner of this city. Let’s be faithful watchmen – not driven by fear but compelled by love.

London is waiting. The Spirit is moving. Will we take up the fire?
