We all wind up drawn to what we're afraid of, drawn to try to find a way to make ourselves safe from a thing by crawling inside of it, by loving it, by becoming it.
God does not have to come and tell me what I must do for Him; He brings me into a relationship with Himself where I hear His call and understand what He wants me to do, and I do it out of sheer love to Him. . . When people say they have had a call to foreign service, or to any particular sphere of work, they mean that their relationship to God has enabled them to realize what they can do for God.
