Post modern Spirituality

A very interesting conversation last week. We repeated a focal point and leaflet, revamped slightly, about hard places. People are invited to take a small stone and symbolically place it in a situation that is hard. One of the regulars to the Hub commented she knew exactly where she was going to put her stone. That sounded to me like an invitation to engage in conversation. She shared the problems she was having with a neighbour and finished with the comment 'If that doesn't work can I bring it back and exchange it for a Voodoo doll!' It wasn't a deeply serious conversation by any means, but it make me think. Postmodern spirituality is often a mishmash of different ideas and the boundary between that which is 'holy and of God' and that which clearly isn't is blurred. Questions I am reflecting on as a result are;
In our instant fix society how do we encourage people to wait on the Lord for answers rather than dash off in search of an alternative that might work better?
Does this sort of thinking mean the boundaries between the sacred and secular are coming down, but at what cost? How can we encourage someone's spiritual search to be distinctly Christian?
