“Love must be sincere. Hate what is evil; cling to what is good. Be devoted to one another in love. Honour one another above yourselves. Never be lacking in zeal, but keep your spiritual fervour, serving the Lord. Be joyful in hope, patient in affliction, faithful in prayer. Share with the Lord’s people who are in need. Practice hospitality.

Bless those who persecute you; bless and do not curse. Rejoice with those who rejoice; mourn with those who mourn. Live in harmony with one another. Do not be proud, but be willing to associate with people of low position. Do not be conceited.”

Romans 12:9–16

Paul reminds us in Romans 12 that transformation by God’s grace doesn’t happen in isolation — it happens as we live together as the body of Christ.

Using the image of a body, Paul shows us that life and growth come through connection. When we choose to live disconnected from the church, we cut ourselves off from the very place God uses to form us. What holds the body together is love — not the fragile, emotional love our culture often celebrates, but agape love: self-giving, sincere, and active.

Paul describes love that is honest and discerning, devoted like family, enthusiastic in action, patient in suffering, faithful in prayer, generous with resources, hospitable to others, and willing to share both joy and pain. This kind of love isn’t something we produce by trying harder; it flows from the grace we’ve already received in Christ.

True love commits to people for the long haul. It challenges, supports, celebrates, and suffers together. As we live this way, we become a visible picture of God’s kingdom — a city on a hill — transformed together by grace.

Therefore, I urge you, brothers and sisters, in view of God’s mercy, to offer your bodies as a living sacrifice, holy and pleasing to God—this is your true and proper worship. Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is—his good, pleasing and perfect will.
- Romans 12:1-2

Romans 12 marks a significant turning point in Paul’s letter. After laying out the gospel of grace, Paul turns to the life that flows from it. Everything hinges on one word: therefore. Christian ethics are not about earning God’s favour, but responding to God’s mercy. As someone once put it, “religion is grace; ethics is gratitude”.

And what is gratitude? Paul urges the people of the church to offer their bodies as “living sacrifices.” For his original hearers, this would have been a paradox. Sacrifices were dead bodies, bleeding out on an altar. So what could a living sacrifice be? Only your whole self and your everyday life given over to God. In other words, not just your “Sunday self,” but our work, relationships, choices, and habits.

The problem with living sacrifices is that they keep trying to crawl off the altar. We are not set up for sacrifice but self-interest, with deep patterns and instincts that shape how we work, rest, play, and what we do when things don’t go our way. If the same outcomes keep repeating, it’s probably not a coincidence—it’s a pattern.

So Paul asks listeners - and us - not to pattern our lives according to the world. It is as if to say, we must realise that many of us are already sacrificing our lives without knowing it, offering them up to careers, success, or autonomy. These things are false gods, not just because they have no right to ask for our worship, but because they haven’t done for us what Jesus has. Jesus himself offered everything—taking his hands off his own life and trusting the Father completely. When you know that grace, then offering your life back to God becomes the only reasonable thing to do.

And if you don’t yet know that grace, then what? Real transformation doesn’t begin with trying harder, but with being deeply grasped by what has already been done for you, without even knowing that you need to ask.

When the angel says Jesus will receive “the throne of His father David,” it tells us something very concrete. The coming of God’s kingdom arrives in the shape of an ideal King ruling His people.

“Son of David” draws together Israel’s best experiences of leadership—its golden age—as well as its hopes, promises, and yes, even its disappointments. It narrows the story down to one royal line, one covenant, one expectation, and finally one King.

Because David wasn’t just any king—he was the king and God’s promise to David wasn’t only for David, it was for the whole nation. A forever King means a forever people. This extends this vision of kingdom beyond the ordinary existence of this world as we now know it.

So when Mary learns her child will sit on David’s throne, she hears more than a personal blessing. She hears more than a description of what her son will be. She hears that God’s long-awaited King is finally coming, and that God’s long-awaited restoration is beginning. God’s plan is grounded and embodied and involved in our lived daily experience.

We follow:

a wise and righteous King.

a King worthy of our loyalty and obedience.

a King whose reign brings peace, healing, and transformation.

a King who expects us to live by a distinct rule.

a King whose kingdom never ends.

A king is meaningless without a people. We—the Church—are King Jesus’ people. That gives extraordinary dignity to everything we do.

This Advent, we aren’t just looking back to a baby in a manger. We’re looking forward to a King on a throne— a King who reigns even now, and whose reign will one day be gloriously obvious to all.

When we pray “Your Kingdom come” we are asking for something specific and concrete. It is a vision that first appears with King David and the kingdom of Israel. Then the son of David, when on earth as he gathered his followers, put reality to this vision. Today we pray that Jesus’ vision of the kingdom will be formed in London through us. We know that the Kingdom will some day come in completeness.
