The discernment for the worker himself is I am God’s, therefore I am good for no one else; not good for nothing, but good for no other calling in life. “No man, having put his hand to the plough, and looking back, is fit for the kingdom of God.” If you have taken on you the vows of God, never be surprised at the misery and turmoil that come every time you turn aside. Other people may do a certain thing and prosper, but you cannot, and God will take care you do not. There is always one fact more known only to God.
– Chambers, Oswald: Approved Unto God
