The last time I was stopped at a police roadblock was in Zimbabwe in 2007. In fact we were stopped at a number of them, mostly while we were en route to Victoria Falls. This morning we were stopped in the dark just outside Khartoum while driving to visit the new Diocese of Wad Medani. Our passports were taken while another bloke with a big red stick poked his head through the car window, saw the white man and asked where we were from. “England” elicited a frown and a sucking of teeth – after which he said, “Football?” I wondered if giving the wrong answer might make our plight worse. “Liverpool,” I said with a smile. He looked at me and said: “You'll never walk alone.”

That's globalisation for you!

Further on in the two-and-a-half hour journey and I got another lesson in how not to jump to conclusions… or misreadings.

The road runs alongside the Blue Nile and either side of it runs a sort of 'ribbon development' in the making (as well millions of plastic bags and bottles, accompanied by an exotic range of animal carcasses at various stages of decay). What I thought I was looking at as we drove (hairily, at 60mph, as if we were playing dodgems) was strings of derelict buildings surrounded by low and deserted compound walls. Another bit of unfinished or neglected infrastructure? Or evidence of communities now abandoned because of conflict or expulsions?

Neither, in fact. These were buildings and walls in process of being constructed. What I saw as falling down was actually being built up. My prejudices – of which I am not proud – were confounded yet again. And it made me wonder how many other such judgements I make that reality might embarrass. All I did was ask the Bishop of Khartoum (our host) and he, unaware of my thinking, just told me people find it cheaper to buy land and gradually build houses outside the city. I didn't know how to read what I saw.

Having cleared that up – and resolving to ask before judging – we received wonderful and generous hospitality at the Cathedral in Wad Medani. This diocese was established only a couple of years ago, carved out of Khartoum which was imply too big. It is still enormous. And it still covers territory that is currently subject to war – creating enormous numbers of displaced people. All the clergy, including the Diocesan Bishop, are volunteers – they are setting the whole thing up from scratch and, already poor, have next to nothing.

But, what they do have is faith in God, a strong commitment to serve the people of that area, and a refusal to give in to any easy option. They are remarkable. Why is it always the church that runs (for example) literacy projects and creates community for people who don't belong to them? It seems that wherever you go in the world, the church is there, using its often meagre resources for the betterment of their people.

At the moment this diocese depends on links with dioceses like mine even to produce a modicum of working capital. They are explicit about wanting to be self-sufficient, but need to get the resources (for example, build shops and a guest house on their land in order to raise a little revenue to then be able to fund clergy and further sustainable projects).

If you know anyone rich who wants to see some cash go to very impressive people in a tough part of the world, point them in my direction.

And now for a meeting with the bishops of Sudan – excluding the Bishop of Kadugli who is now based in the South and cannot return to his own diocese because of the war going on there. More anon.

(Oh… and I have just re-read Joachim Gauck's little book on Freiheit: Ein Plädoyer – basically, we need to know how to use freedom for and not just enjoy freedom from – before moving on to Walter Brueggemann's The Practice of Prophetic Imagination. It's all fun, fun, fun…)
