On limits and obstacles

Reading this morning about limits and obstacles, I am coming to understand the difference between the two.

I've known people over the years who object to limits (I'm thinking of fidelity in marriage as an example, or certain more permissive child-rearing practices) and see them as obstacles to growth. But in fact thoughtfully constructed limits can serve as a way to channel and focus energy.  A river in flood, for example, is a highly destructive and random force; a river properly channeled can provide energy for thousands of homes.

The dailiness of life and its challenges can put up lots of obstacles to faith.  But the conscious discipline of a daily practice -- whatever it might be -- can serve as a frame to focus and channel the work of the spirit, so it shines through whatever obstructions may occur...
