A colleague of mine and I were recently chatting about fostering an active spirituality in our congregations. He said, "We're so busy living the life we believe we're suppose to live, we don't have (or take time) to discover the life God has already created in us." Yes, we too often live the shoulds and oughts that keep us always looking elsewhere than where the life we seek is really taking place--right here, now . . . within us. The Holy Spirit offers an inner witness, if we know where to look.
If this is what you're looking for, I recommend a remarkable series called: Bridges to Contemplative Living with Thomas Merton. It's an 8 booklet set of 8 sessions each for private or group reflection. I'm using it in my spiritual formation course at the university now and plan to use it in the congregation in the future.
For those seeking to go deeper still, the author of the 14th century Cloud of Unknowing (an English spiritual director), writes a little book called, "The Book of Privy Counsel." Here's a link to a lovely new translation of both Privy and the Cloud. In the second chapter he summons us to focus not on what we are, but that we are. That is a spiritual practice with revolutionary consequences.
