Who are we?

Went to morning worship at W/S yesterday morning - got introduced to more people - Mary, Myra & Walter; Hazel, Edna and Gwen, Doreen and possible Julia! So many new names - and I have such a poor memory for names! I'm sure that next week they will all expect me to remember them and I'll fail!! Hopefully they'll be understanding.
A good service led by a retired minister - extolling us to dance and praise God and David did - both in church and in 'the world' (how I hate that term!)
The setting up of church 'walls' - either actual or metaphorical means that we restrict ourselves from working with God in his world, in his creation and with his all his people. The 'us' and 'them' mentality is responsible for creating a perceived 'elite' which has degenerated into a ghetto mentality for the established church, which is seen as irrelevant to those who have no contact with it.
The big question is - are we prepared to tear down the walls and if we do, are we sure enough of the gospel to not get engulfed by the secular society in which we live?
