Acts 16:4

And as they went through the cities, they delivered . . . the decrees . . . And so were the churches established in the faith, and increased in number daily--not the churches, but the number of their members, by this visit and the written evidence laid before them of the triumph of Christian liberty at Jerusalem, and the wise measures there taken to preserve the unity of the Jewish and Gentile converts.

It is some rebuke to Barnabas that after he left Paul we hear no more of him, of what he did or suffered for Christ. But Paul, as he was recommended by the brethren to the grace of God, so his services for Christ after this are largely recorded; we are to attend him in this chapter from place to place, wherever he came doing good, either watering or planting, beginning new work or improving what was done. Here is, I. The beginning of his acquaintance with Timothy, and taking him to be his assistant (Act 16:1-3). II. The visit he made to the churches for their establishment (Act 16:4, Act 16:5). III. His call to Macedonia (after a restraint he had been under from going to some other places), and his coming to Philippi, the chief city of Macedonia, with his entertainment there (Act 16:6-13). IV. The conversion of Lydia there (Act 16:14, Act 16:15). V. The casing of an evil spirit out of a damsel (Act 16:16-18). VI. The accusing and abusing of Paul and Silas for it, their imprisonment, and the indignities done them (Act 16:19-24). VII. The miraculous conversion of the jailer to the faith of Christ (Act 16:25-34). VIII. The honourable discharge of Paul and Silas by the magistrates (Act 16:35-40).

16:4-5 Paul and Silas faithfully communicated the decisions of the Jerusalem council. The wisdom of the decision was indicated as the churches were strengthened in their faith and grew larger every day (cp. 2:41; 4:4; 5:14; 6:1; 9:31; 21:20).
