I have just listened to an interview of Archbishop of Canterbury, Justin Welby, given at New Wine this summer. Here is a link. It is well worth a listen.
Of the many things that struck me was the phrase, "the church is not a refuge for saints but a home for sinners." This comment was made about churches that try and get everything internal sorted before reaching out to those around them. He spoke about how we sometimes put off doing those things we know we should do yet are less than enthusiastic about. He even admits to ironing socks to delay getting down to writing an important talk!
His encouragement was to keep pressing on with Kingdom work recognising that when you put a load of sinners together you don't get saints, it's not multiplication but addition.
May God give us the grace and courage to press on with his Kingdom work. May we not be so inward focused that we forget the Great Commission to go and make disciples of all nations.
