Charles Spurgeon Commentary Acts 16:10

"And when he had seen the vision, straightway we sought to go forth into Macedonia, concluding that God had called us to preach the gospel to them." — Acts 16:10 (ASV)

In the vision, the man prayed, Come over into Macedonia, and help us. The best help that Paul could render to the Macedonians was to preach the gospel unto them. The best help you can give men socially is to help them religiously; and the best religious help is to preach the gospel to them.
