19 And they came down to Ephesus and he left them there: and he himself went into the Synagogue and had a discussion with the Jews. 20 And being requested by them to be there for a longer time, he said, No; 21 And went from them, saying, I will come back to you if God lets me; and he took ship from Ephesus.

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.
