While reading an old issue of Discipleship Journal from 2002 I came across this story:
The famed 19th-century evangelist D.L. Moody was once asked if he was filled with the Spirit. "Yes," said Moody, "but I leak."
Several paragraphs later it goes on to explain:
To speak of "leaking" doesn't mean the Holy Spirit somehow seeps out through our pores; it is an acknowledgment that operating in a fallen world wears on (our) relationship with God.
I can acknowledge that sometimes I leak. I am so grateful that when I am weak, or leaking, He can make me strong. Only He can fill the cracks in my armor that come about from daily use.
