Now I will come to you when I pass through Macedonia . . . And it may be that I will remain, or even spend the winter with you, that you may send me on my journey, wherever I go . . . But I will tarry in Ephesus until Pentecost. For a great and effective door has opened to me, and there are many adversaries. ~ 1 Corinthians 16:5-9
Paul had a plan to reach the major cities of his day. In a conversational manner, he describes his plan to start in Macedonia, then move south to Corinth, and finally visit Asia Minor and the major port city of Ephesus, where "a great and effective door opened" to him.
Effective leaders don't drift from one place to another. Paul had a plan to impact major cities that would in turn influence those who visited these cities. He focused on the metropolitan areas, knowing that well-trained followers would bring God's message to the smaller towns and villages in the region.
Leaders can do anything, but they can't do everything. Paul did not spend his energies haphazardly, but charted the course to reach the Roman Empire in his lifetime. What kind of plan do you have?
