On this exact day back in 33 AD, Jesus rose from the dead (Resurrection Sunday was 05 April that year too). That’s 1993 years ago. Happy Easter for today. And let’s throw the biggest party ever in seven years to celebrate 2000 years of salvation available to all! ✝️

[Mayor of London, Sadiq Khan @MayorofLondon]

The Passion of Jesus returned to Trafalgar Square on Good Friday - an epic retelling of Christ’s journey to the cross with a cast of more than 100 actors and volunteers.

Londoners and visitors gathered in the heart of the city to witness this powerful reenactment for Holy Week.

John Wesley's accountability questions, from the early #Methodist bands and classes, are a fantastic guide for anyone wanting to set up #discipleship or #accountability groups. Check them out here. #JohnWesley

@IanPaulFletcher @afneil It’s actually the facilitation of money laundering through global tax havens.

The basic math of leadership:

1. Figure out the 80/20
2. Take action at 70% confidence
3. Compound by investing in 1% improvements

Combine them all to become one in a million.

A pleasure to be with @RwandaLocalGov today in Rwanda facilitating this…

[Ministry of Local Government | Rwanda @RwandaLocalGov]

Today, MINALOC, in collaboration with One Rock International, conducted training on servant leadership, aimed at strengthening leadership capacity and promoting effective service delivery. Trainees were officials from City of Kigali, Provinces, and senior managers from MINALOC.

Happy 25 March everybody! May this day have, dare I say it, a sacral quality for you all…

[Tom Holland @holland_tom]

It's 25 March - the day everything happened

[Mark Williamson @markonerock]

So @EE can you please explain why my TV package is not working, and what error AJ963 means? Otherwise I’m paying for the sport add on and can’t watch the match tonight.

[Mark Williamson @markonerock]

Happy birthday you guys!

[Third Space @ThirdSpaceMin]

We had a wonderful time yesterday celebrating our birthday, sharing stories, meeting people, giving thanks & eating cake! Thanks to all who came 🎉🎂

[Mark Williamson @markonerock]

Tonight @SanctuaryMCHW we're meeting online to discuss how Jesus alone is the mediator between God and humanity. It's actually Daniel Larbi leading (contrary to this lovely picture of Jamie). But you're welcome to come join us. DM for the Zoom link if you're a Londoner.

[Mark Williamson @markonerock]

Last night I caught up with an old friend in Rwanda and had this fantastic setting and view for our dinner. Good night out!

[Mark Williamson @markonerock]

Lovely to be back in Rwanda. The view is good and the weather is great (apart from the occasional thunderstorms). Looking forward to a big weekend of training coaches and starting a new Institute cohort.

[Mark Williamson @markonerock]

Still chance to join us tonight for this!

[Mark Williamson @markonerock]

I’ll be teaching this online on Thursday evening. Come along if you’re curious about the whole ‘saved by faith versus but good works are a requirement’ dilemma that the church has often grappled with.

[Sanctuary @SanctuaryMCHW]

Come join us for this online discussion this Thursday evening. If you’re #London based and aged 20-40 we want to hear from you! We’re exploring the #Reformation and how it’s radically affected our #spirituality. DM us for the zoom link. #faithvworks

[Mark Williamson @markonerock]

@LNJStokes @JusBrierley Or as we like to say @SanctuaryMCHW let’s be followers of Jesus who are therefore exploring spirituality and justice (and we throw in leadership too!).

Two ways to change people's lives:
