I almost fell into the trap.  
"I'm not overseas," I thought.  "How can I 'report from the front line'?"

Schoolgirl error (as we say in the UK).

All mission is local (as we say in Radstock).

And sure enough, I've recently been re-envisioned for our local 'front line' (Chelsea, London, UK), not least by spending a week apparently some way back from the front line - helping to lead a team of Christian university students doing the behind-the-scenes tasks of a new summer kids' camp.  

Others have reflected thoughtfully on summer camps (like here for example), and on the bigger 'front line' question (like here and here) so check those out

One thing I particularly liked about camp was that there were a few key local churches at the heart of it - with other churches already planning to recruit kids, students, leaders and cooks for next summer.  It helped to make it crystal clear that this was still very much a frontline of mission - away from home perhaps, and with gospel and relational opportunities you only find when people are let loose with a full week, a boarding school and grounds and a lot of creativity - but all building on and feeding into the ongoing life and mission of those church families.     

The Lord is kind & wise. "...and he determined the times set for [us] and the exact places where [we] should live. ²⁷God did this so that men would seek him and perhaps reach out for him and find him..."

I'm back home - on my & my church's frontline.  How are you doing on yours?
