New Defender's Study Bible Notes
16:10 we. The first use here of “we” in the narrative, instead of “they,” seems to indicate that Luke, the author of the book of Acts, joined the missionary party at Troas.
16:10 Lord had called us. The Lord’s calling may become evident in different ways. One key principle is indicated here in the calling of Paul to Macedonia in Greece. He was already active, trying to preach in the province of Asia, then in Bithynia; he was not waiting idly at home, hoping to receive a call. The Holy Spirit in some very clear way closed the first two doors, but then opened another, by this special vision. It is sobering to think that if Paul had not been redirected to Philippi and Greece, he might never have gone into Europe and Christianity might have remained primarily an Asian religion. But God had other purposes.
