In little more than ten years St. Paul established the Church in four provinces of the Empire, Galatia, Macedonia, Achaia and Asia. Before AD 47 there were no churches in these provinces; in AD 57 St. Paul could speak as if his work there was done, and could plan extensive tours into the far west without anxiety lest the churches which he had founded might perish in his absence for want of his guidance and support.
The work of the Apostle during these ten years can therefore be treated as a unity. Whatever assistance he may have received from the preaching of others, it is unquestioned that the establishment of the churches in these provinces was really his work. In the pages of the New Testament he, and he alone, stands forth as their founder. And the work which he did was really a completed work. So far as the foundation of the churches is concerned, it is perfectly clear that the writer of the Acts intends to represent St. Paul’s work as complete. The churches were really established. Whatever disasters fell upon them in later years, whatever failure there was, whatever ruin, that failure was not due to any insufficiency or lack of care and completeness in the Apostle’s teaching or organization. When he left them he left them because his work was fully accomplished.
This is truly an astonishing fact. That churches should be founded so rapidly, so securely, seems to us today, accustomed to the difficulties, the uncertainties, the failures, the disastrous relapses of our own missionary work, almost incredible. Many missionaries in later days have received a larger number of converts than St. Paul; many have preached over a wider area than he; but none have so established churches. We have long forgotten that such things could be. We have long accustomed ourselves to accept it as an axiom of missionary work that converts in a new country must be submitted to a very long probation and training, extending over generations before they can be expected to be able to stand alone. Today if a man ventures to suggest that there may be something in the methods by which St. Paul attained such wonderful results worthy of our careful attention, and perhaps of our imitation, he is in danger of being accused of revolutionary tendencies.

Seems to me that Paul in his letters often speaks of the power of the Holy Spirit being the main factor in any of the success of his evangelization and church planting. We might do well to be used of the Holy Spirit we find in the Bible (not the spirit of the 3-ring circus of some “evangelical churches”) and He might just accomplish such results through us as well.
