Macedonia, as part of Greece, was distinguished by culture. In particular, the search for the true God was as strong there as throughout Greece.
There was the same powerlessness both to know God and to serve Him in truth. Therefore the help of the preachers of the true faith was urgent there.
It is therefore no wonder that not only Paul, but all who were with him, unanimously resolved to depart for Macedonia. Even the writer of Acts himself, who until now had modestly given no sign of himself, says: "we resolved to depart for Macedonia."
Bishop Michael, however, supposes that the writer of Acts probably joined the companions of the Apostle Paul precisely there, in Troas.
Saint John Chrysostom, noting the special character of the revelation, says: "Where persuasion was easy, God appears in a more human manner. Where there was greater difficulty, He appears in a more divine manner.
"Thus, when Paul needed to preach, a dream was given to him for this. But when he needed to be restrained from preaching, the Holy Spirit revealed this.
"So it was with Peter, when the Spirit said to him: 'Rise and go' (Acts 10:20). For the Spirit did not perform easy things, but a dream was sufficient for this.
"So also with Joseph, when it was easy to persuade him, there was a dream. But for others there was a vision (see Mt 2:13). So also with Cornelius and with Paul himself."
The Holy Spirit now led the apostles into Europe. They did not yet know exactly where they would have to sow the word of the Gospel.
They only surmised that, in the near future, an entirely different sphere would open for their activity. Therefore they went directly westward toward the maritime harbor of Troas.
They finally arrived there, proceeding along the border between Mysia and Lydia. The city of Troas was rich and flourishing.
Traces of its prosperity remain to this day. There one can see remains of the harbor, ruins of temples and theaters, and an aqueduct from Mount Ida, rich in springs according to Homer.
Entering Troas and seeing the sea before him, Saint Paul could foresee that he would soon have to sail upon its waves. But where? This remained unknown.
And then, one night soon after Paul's arrival in Troas, a vision appeared to him. A Macedonian man stood before him and said: "Come over to Macedonia and help us."
Although this vision occurred at night, Saint Paul did not receive it in sleep. In all probability, he was counted worthy of the vision during prayer, while asking that his further path be directed.
On the basis of the book of the Prophet Daniel, one may think that the Angel of Macedonia, zealous for the good of the people under his protection, asked God to send Paul to him.
And the prayer of the Angel was heard. "By the action of His almighty power, God brought Saint Paul into a special ecstatic state.
"In such a state a man becomes capable of perceiving manifestations of the higher spiritual world. The apostle understood the desire of the Angel, which in this case expressed the will of God."
