This Saturday Catrina and I are hosting a 'Matthew Party' (named after the disciple Matthew who was constantly inviting people to parties). We've invited all the neighbours from the road we live in, along with some other friends, over for drinks and food any time between 2 and 8pm. We've got no idea who is going to turn up, or when, but I'm really looking forward to seeing how God will use it and what conversations we'll end up having. We'll also take the opportunity to invite all of our neighbours to the various Christmas events.
I know that quite a few Lifegroups are organising parties too. If you haven't got one organised for your neighbours, why not consider inviting them round on Sunday 19th and tying it in with inviting them to one of the guest meetings on that day. You just never know what God will do!
