"like a spring whose waters never fail"

I came across this passage again this morning and thought it would fit well with my retreat concept ("living water"), so I want to remember it:

"If you do away with the yoke of oppression, with the pointing finger and malicious talk, and if you spend yourselves in behalf of the hungry and satisfy the needs of the oppressed, then your light will rise in the darkness, and your night will become like the noonday.

"The Lord will guide you always; he will satisfy your needs in a sun-scorched land and will strengthen your frame. You will be like a well-watered garden, like a spring whose waters never fail." (Is 58.9-11)

Speaking of retreats, the Jesuits at Loyola invited me to their presentation tomorrow on retreats for the homeless. I'm looking forward to that, both to see what they've come up with and to get to know them better.
