NASA has done something amazing. One of their spacecraft has made a movie of the Moon passing in front of the Earth as it orbits our planet.
This was not a simple achievement! To see things from a suitable distance you need to have a camera position many times further away than the Moon.
A hundred and twenty times as far as the Moon would be fine, and this is what NASA has done.
Just think, the Moon circles the Earth once every 28 days, drawing out a circle half a million miles across. From our perspective the Moon glides past the starry constellations of the night sky.
But if we could travel far enough away we'd see the Moon sometimes one side of the Earth, sometimes the other, but never straying very far.
First, sit back and watch the movie. Then come back and read more of this blog post to find out how it was done.
In the year 1610 Galileo saw four points of light changing position night by night when he turned his telecope on the bright planet Jupiter. He realised that these points of light were circling Jupiter. It was final proof that not all celestial bodies orbit the Earth and therefore our planet cannot be the centre of the universe as was supposed by the mediaeval church.
This is exactly how the Moon would be seen to behave from a camera 31 million miles away, and this is what the video shows.
Here's how this amazing video was made. The Deep Impact spacecraft successfully investigated a comet in July 2005, but with its primary mission completed NASA decided it could usefully perform two further tasks. The Deep Impact team realised that they could also use the spacecraft to take images of the Earth and Moon, and they commanded the craft to take a series of images through four different colour filters at 15 minute intervals. Afterwards, the images were combined to make full colour versions and a series of the colour images were put together to make the video.

Frank Viola on Don Francisco
In a recent blog post Frank Viola recommends one of Don Francisco's songs, 'He's Alive'. And indeed this is a wonderful song.
Another of Don's great songs is 'And the Spirit Sings', it's one of my all-time favourites and it carries a gentle but strong message that meeting in freedom can be a very special experience because it causes the Holy Spirit to sing. That has been true in my experience, and in Frank's, and in Don's, and in the lives of so many of the people I know and love.
To be in a meeting at home, where Yahshua is welcomed along with everyone else, that is a supreme privilege.
Meetings like this have been the absolute pinnacle of my life - and that's no exaggeration! What can equal his palpable presence amongst his people? He is enthroned in the splendour of holiness yet he is intimately one of us - and the Spirit does indeed sing! Wonderful, wonderful times together over and over again. (Of course it's not being at home that makes this possible, but our freedom in one another's presence and the Lord's freedom amongst us.)
'And the Spirit Sings' can be found on Don's album 'Come Away'. If you like Don's style and you've never heard this particular track I strongly recommend you buy 'Come Away', the other songs are great too. The CD's available on Don's website. As I write, the homepage provides 'He's Alive' as a free listen. Go and hear it! Maybe Don will consider putting 'And the Spirit Sings' up there too - how about it, Don?
If you want to catch the aroma of meetings of this kind (just a hint of what they're like) read the notes on some of our past meetings. But like a great dish, a meeting in which he's powerfully yet gently present is something that can't be fully appreciated without tasting it.

FAMILY - Travelling with friends
Previous | Part 1 of a series | Next
Since 27th July Donna and I have been travelling around the UK with friends from Florida. This has been a time of blessing and fun for me personally, a time I'll always remember.
We have packed so much rich experience into just a few short days of living. And it seems to me that this is the way the whole of life should be lived. Life is short, so everything we experience in it should be treasured as a special privilege.
The holiday is not yet over, but it's getting closer to the end. Thinking about that brings some sadness, but reflecting on what we've done together brings great joy. Perhaps all of life is like this holiday. It has a beginning and a not-yet-experienced ending. It is a journey. It's a far richer journey when we dwell on the good things and allow the less good to flow quietly into the past and learn patience, wisdom, and trust in the process. The quality of our lives, like the quality of a holiday, is based partly on what we choose to hold onto and what we choose to let slip away without bitterness, anger or regret.
Here's a list of the outstanding things we've included so far, the things to remember and dwell on later.
So many happy memories, and still a few more to come. Life is rich, and good, and full. Life is like a meadow in the summer, filled with every kind of flower, dancing with butterflies and shimmering on a hot, dry day. As I write, the rain is pounding on the conservatory roof - but that, too, is a wonderful thing, what a sound! In the garden it's soaking into the good earth and making the plants flourish. They need the sunshine, but they need the rain too. Sunshine and water combining to generate abundant and carefree life. The rain today and perhaps the sunshine tomorrow.
We're rather like those plants, we need sunshine and rain in our lives to truly thrive.

Biblical Church - Beresford Job
Over the last few weeks I've been reading 'Biblical Church' by Beresford Job who lives north-east of London and meets with the Chigwell Christian Fellowship. And what a fascinating read!
The book is well argued and provides plenty of references both to Bible passages and to well known and respected theologians and Biblical commentators. Job uses this as a technique again and again, pointing out that his conclusions about the meaning of Bible texts and Koine Greek words and constructions are in agreement with expert opinion. Job is claiming nothing new, but he is stoutly proclaiming that as believers we are duty bound to put into practice whatever we see in the New Testament concerning church meetings and governance.
He makes it clear that this means meeting in homes not specially constructed buildings, having small meetings as the norm (tens rather than hundreds or thousands), and the absence of any kind of hierarchical structure. He further points out that it's normal for a local body of believers to eat together as well as worship together, and that meetings are not supposed to be a 'service' led from the front, but instead are an expression of community involving everyone in an active, not passive way.
On the whole, this book complements Frank Viola and George Barna's best-seller, 'Pagan Christianity'. The Viola/Barna book explains how the Church came off the rails in the first place, and also describes the changes necessary to get us back on track. Job's work takes the revised, corrected 'version' of local church and fleshes it out with recommendations on how to get from A to B, what difficulties are likely to be encountered, and how to avoid the major pitfalls. 'Pagan Christianity' could be seen as a theoretical analysis, 'Biblical Church' as a practical handbook (although there is plenty of overlap).
There is one area where my understanding differs from Job's, and that concerns the place of women in church life. But as Job himself says, there will always be differences of understanding and differences of emphasis in the Church, but the truly important thing is that we can (and must) love one another through differences of this kind. We must extend to one another the right to be different.
My advice? Read both these excellent books!

MIT's Simile
MIT stands for 'Massachusetts Institute of Technology', right? That's widely known.
But what does Simile stand for? If you don't already know you will never guess, it stands for 'Semantic Interoperability of Metadata and Information in unLike Environments'.
Sooo... why exactly am I interested in this? It has something to do with my day job.
A portion of that day job is hunting for useful technology for the web development team I'm part of, we create intranet websites for Unilever. The thing is, MIT's Simile project 'seeks to enhance inter-operability among digital assets' and is 'fully committed to the open source principles of software distribution and open development'. To put this another way, they develop some very cool applications that work together and they release them for use and adaptation by anyone, anywhere, for any purpose.
The application that first caught my eye is called 'Timeline' and it is amazing. The code is stored on MIT's servers so there's nothing to install and download. The data is stored locally as an XML file. If you're not a techie person and you're still following along, just take a look at a couple of their example timelines, one on religions, the other on dinosaurs. They are so cool. Just drag them sideways with the mouse.
The other applications are good too, if you develop websites many of these may be a perfect way of making your site truly impressive, just by embedding stuff the way you would with Google Maps or You Tube.
Exhibit - displays data as presentation graphics. Gadget - summarises large XML datasets. Welkin - displays data in mathematical graph form. Fresnel - is a developers' tool, a vocabulary. And there are many other projects and services available, just take a look at the Simile home page.
Quite apart from the effectiveness of the individual offerings and the fact that they are free to use, the Simile project showcases how web components should be designed and built. Congratulations and thanks to MIT and to everyone working on aspects of the Simile project.

Great Doddington - Table and vine
This was a great evening. At one point Jody brought oil, feeling we should anoint Peter - so that's exactly what we did.
Rachael decribed a vision of a long, long trestle table in what appeared to be a mediaeval castle hall. The table had an almost completed jigsaw laid out along its entire length. The jigsaw was composed of many scenes from life, and each scene contained something of Jesus. At a time of particular difficulty there was a beam of light or a glass containing the water of life, and in a scene when all was well there was a little bird sitting in a tree or some other little, joyful feature. The long jigsaw represented a person's lifetime, from birth to death.
At the end, the man making the jigsaw had only a few pieces left to add.
Chris saw that there were many tables and they all centred on Jesus and each long jigsaw was actually joined into him. So the place where the jigsaw ended, the point of death, was also the place where it joined with the centre and in reality connected fully with Christ.
We reflected on these pictures and considered again how we are grafted into the one true vine (John 15). We really are a royal priesthood!
