We are so good at dividing things up. We put people - and churches and all sorts of other things - into categories. They are filed under a particular heading - but God doesn't recognise the distinctions we make.
I like Barbara Brown Taylor's comment (in An Altar in the World, Canterbury Press, 2009, p. 15) - "Human beings may separate things into as many piles as we wish - separating spirit from flesh, sacred from secular, church from world. But we should not be surprised when God does not recognise the distinctions we make between the two. Earth is so thick with divine possibility that it is a wonder we can walk anywhere without cracking our shins on altars."
God engages with us wherever we are, whatever we are doing.
