acts 16:9 And a vision appeared to Paul in the night; There stood a man of Macedonia, and prayed him, saying, Come over into Macedonia, and help us. - Free Bible Online

      9, 10. a vision appeared to Paul in the night--while awake, for it is not called a dream.
      There stood a man of Macedonia, and prayed him, saying, Come over into Macedonia, and help us--Stretching his eye across the Ægean Sea, from Troas on the northeast, to the Macedonian hills, visible on the northwest, the apostle could hardly fail to think this the destined scene of his future labors; and, if he retired to rest with this thought, he would be thoroughly prepared for the remarkable intimation of the divine will now to be given him. This visional Macedonian discovered himself by what he said. But it was a cry not of conscious desire for the Gospel, but of deep need of it and unconscious preparedness to receive it, not only in that region, but, we may well say, throughout all that western empire which Macedonia might be said to represent. It was a virtual confession "that the highest splendor of heathendom, which we must recognize in the arts of Greece and in the polity and imperial power of Rome, had arrived at the end of all its resources. God had left the Gentile peoples to walk in their own ways (Ac 14:2). They had sought to gain salvation for themselves; but those who had carried it farthest along the paths of natural development were now pervaded by the feeling that all had indeed been vanity. This feeling is the simple, pure result of all the history of heathendom. And Israel, going along the way which God had marked out for him, had likewise arrived at his end. At last he is in a condition to realize his original vocation, by becoming the guide who is to lead the Gentiles unto God, the only Author and Creator of man's redemption; and Paul is in truth the very person in whom this vocation of Israel is now a present divine reality, and to whom, by this nocturnal apparition of the Macedonian, the preparedness of the heathen world to receive the ministry of Israel towards the Gentiles is confirmed" [BAUMGARTEN]. This voice cries from heathendom still to the Christian Church, and never does the Church undertake the work of missions, nor any missionary go forth from it, in the right spirit, save in obedience to this cry.
