Ephesus was a city in which many Jews took up residence
+ At the close of his second missionary journey (about A.D. 51)
+ He remained, however, for only a short time = Hastening to keep Pentecost @ Jerusalem
+ He left Aquila and Priscilla behind him to carry on the work of spreading the gospel.
+ Paul reached Ephesus from the "upper coasts" (i.e., the inland parts of Asia Minor)
+ Tarried here for about three years
+ Probably during this period the seven churches of the Apocalypse were founded
+ Not by Paul’s personal labours, but by missionaries whom he may have sent out from Ephesus, and by the influence of converts returning to their homes.
+ He sends for the elders of Ephesus to meet him
+ Ephesus is not again mentioned till near the close of Paul’s life = [1 Tim. 1.3]

While there is a great deal which we could focus on in this passage
+ I want to focus on "Paul the pastor"
+ Paul fulfilled so many roles in the history of Christianity
+ Theologian / Prophet / Healer / Preacher = Missionary
+ CHURCH PLANTING MISSIONARY = Model for so much of missions today
+ [17-25] = How touching a scene = How the tears must have been flowing!
+ You can really see his "pastor’s heart" in = [26-32]
What was driving him?
+ v.26 = The idea of being God’s watchman = A sentinel on the city walls / hilltops
+ The "outlooker" for those who might come from without and besiege the city
>>> ISBN, W. M. Christie, "watchman"
+ Consider = Ezek. 3.17-19 = But as might be applied to being a PASTOR
And how did he accomplish this? = 
Is this every pastor’s desire? = Should be
+ If you were to trace this idea through the Scriptures
+ To determine what this would mean for the man of God
+ Who was truly determined "to declare unto you all the counsel of God"
+ According to God = Judging by His Word = Suggests the following applications
[Ps. 32.11] = Dictates your attitude = No matter what God says
+ Paul and Ephesus = Going, sewing, growing = Going again
[Is. 46.10-11] = God’s Word is = Sure = Eternal = And His Will WILL be DONE
+ Acts 20:28 (quickview)  Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood.
[Jer. 23.32] = "they"
+ And there is a grave danger in NOT hearkening to God’s counsel
