I found this quote the other day while looking at devotional books on Amazon, and I've already used it in an e-mail, but I figured it was worth posting here, too. The quote is in reference to Hebrews 11:8 "He went out, not knowing where he was going," which is one of my favorite verses about the nature of true faith.
"Have you been asking God what He is going to do? He will never tell you. God does not tell you what He is going to do--He reveals to you who He is. Do you believe in a miracle-working God, and will you 'go out' in complete surrender to Him until you are not surprised one iota by anything He does?"
--from My Utmost for His Highest by Oswald Chambers
