1) Paul’s missionary method was not peculiar to Paul. He was not the only missionary who went about establishing churches in those early days. The method Paul used was followed by his disciples (Timothy, Titus, Silvanus, etc.), and they were not men of exceptional genius. It is only because Paul was a supreme example of the spirit and power with which it can be used, that we can properly call the method “Paul’s Missionary Method”.
2) We possess today an advantage of inestimable importance in that we have the printing press and the whole of the New Testament where Paul had only the Old Testament in Greek.
3) However highly we esteem Paul’s personal advantages or the assistance which the conditions of his age afforded, they cannot be so great as to rob his example of all value for us.”
I will add to the list that we have the same Holy Spirit; the unchanging God. Nothing about Him has or will ever change. In addition, there are present day witnesses of God using the same methods Paul used. If you are interested in learning how God is moving in the same way as He did through Paul, I suggest you read Church Planting Movements – How God is Redeeming a Lost World, by David Garrison.
