T. Austin-Sparks is usually credited with the term. He writes,
“God’s way and law of fullness is that of organic life. In the Divine order, life produces its own organism, whether it be a vegetable, animal, human or spiritual. This means that everything comes from the inside. Function, order and fruit issue from this law of life within. It was solely on this principle that what we have in the New Testament came into being. Organized Christianity has entirely reversed this order.”
The term can also be found in some of the early Plymouth Brethren writers.
