20 And when they asked him that he would remain for a longer time [with them] he did not accede, 21 but bade them farewell, saying, [I must by all means keep the coming feast at Jerusalem]; I will return to you again, if God will: and he sailed away from Ephesus.
22 And landing at Caesarea, and having gone up and saluted the assembly, he went down to Antioch. 23 And having stayed [there] some time, he went forth, passing in order through the country of Galatia and Phrygia, establishing all the disciples.

Commentary on Acts 18:18-23
(Read Acts 18:18-23)
While Paul found he laboured not in vain, he continued labouring. Our times are in God's hand; we purpose, but he disposes; therefore we must make all promises with submission to the will of God; not only if providence permits, but if God does not otherwise direct our motions. A very good refreshment it is to a faithful minister, to have for awhile the society of his brethren. Disciples are compassed about with infirmity; ministers must do what they can to strengthen them, by directing them to Christ, who is their Strength. Let us earnestly seek, in our several places, to promote the cause of Christ, forming plans that appear to us most proper, but relying on the Lord to bring them to pass if he sees good.
