Ever fuel something with carnal energy?

I’m maybe as big a goal-setter as there is.  But more and more I’m getting a healthy suspicion of them.  Here’s one reason:

“But given enough time, something sinister often invades, and the goals begin to haunt their makers. If we reach the goal, we conclude that "God is blessing." The next assumption is "God is in this program," and before long we are serving the program instead of the Lord himself.  People and institutions begin to corrode when fleshly zeal is tied to spiritual goals. We pastors have a propensity for launching our crusades with righteous intent and then fueling them with carnal energy."

My longing for predictable and measurable was poked when I got this in the mail.
