It is recorded in the Acts of the apostles that Arabians, or Arabian proselytes, were present at the Jewish feast of Pentecost. We must therefore go back to Apostolic times to find the beginnings of Christianity in Arabia. Whether these Arabians were from the northern part of the peninsula bordering on Syria, from the dominions of the Arabian king Hareth (Aretas), or came as Jewish proselytes from distant Jewish colonies of Yemen, must ever remain uncertain. In any case they doubtless carried back to their homes something of the Pentecostal message or blessing. The New Testament references to Arabia are not disconnected and unique, but stand in closest relation to the whole Old Testament revelation of God’s dealings with Ishmael and his descendants. In Paul’s letter to the Galatians,[114] he writes, “Neither went I up to Jerusalem to them which were apostles before me; but I went to Arabia, and returned again unto Damascus.” What did the great apostle to the Gentiles do in Arabia? A consideration of this question will give us a better standpoint to review the later rise of Christianity not only in North Arabia, but in Nejran and Yemen. “A veil of thick darkness,” says Lightfoot, “hangs over St. Paul’s visit to Arabia.” The particular part of Arabia visited, the length of his stay, the motive of his going, the route taken and what he did there,—all is left untold. We can draw the map and tell the story of all but the first great journey of the apostle. Certainly the first journey of the new Saul of Tarsus cannot have been without some great purpose. The probable length of his stay, which is by some put at only six months, but which may have been two years,[115] would also indicate some importance in the event. Visions and revelations to this Elijah and Moses of the new dispensation there may have been while he tarried in the desert, but it is scarcely probable to suppose that at this critical juncture in early church history so long a time should have been occupied with these only. Therefore, we find the earliest commentators of the opinion that Paul’s visit to Arabia was his first missionary journey, and that he “conferred not with flesh and blood,” but went into Arabia to preach the gospel.[116] “See how fervent was his soul,” says Chrysostom, “he was eager to occupy lands yet untilled, he forthwith attacked a barbarous and savage people, choosing a life of conflict and much toil.” The idea that Paul went to preach immediately after his conversion is natural; and that he should, as the Gentile apostle, seek first that race which was also a son of Abraham and heir of many Old Testament promises and whose representatives were present at Pentecost, is not improbable.
