"The call of God is like the call of the sea, or of the mountains; no one hears these calls but the one who has the nature of the sea or of the mountains; and no one hears the call of God who has not the nature of God in him. It cannot be definitely stated what the call of God is to, because it is a call into comradeship with God Himself for His own purposes, and the test of faith is to believe that God knows what He is after." --Oswald Chambers, in Not Knowing Whither from the Quotable Oswald Chambers.
