Oswald Sanders (Director of OMF in the 1950s and 1960s) knew D. E Hoste (a missionary to China who knew Hudson Taylor personally)… D.E. Hoste spoke these words to Sanders.
“I more and more see that as we go on in the Christian life, the Lord very often does not want to give us the sense of His presence, or the consciousness of His help. There again Mr. Hudson Taylor helped me very much. We were talking about guidance. He said how in his younger days, things used to come so clearly, so quickly to him. “But,” he said. “now as I have gone on, and God has used me more and more, I seem often to be like a man going along in a fog. I do not know what to do.”
