Centuries before, the pen of inspiration had traced this ingathering of the Gentiles; but those prophetic utterances had been but dimly understood. Hosea had said: “Yet the number of the children of Israel shall be as the sand of the sea, which cannot be measured nor numbered; and it shall come to pass, that in the place where it was said unto them, Ye are not My people, there it shall be said unto them, Ye are the sons of the living God.” And again: “I will sow her unto Me in the earth; and I will have mercy upon her that had not obtained mercy; and I will say to them which were not My people, Thou art My people; and they shall say, Thou art my God.” Hosea 1:10; 2:23.

The Saviour Himself, during His earthly ministry, foretold the spread of the gospel among the Gentiles. In the parable of the vineyard He declared to the impenitent Jews, “The kingdom of God shall be taken from you, and given to a nation bringing forth the fruits thereof.” Matthew 21:43. And after His resurrection He commissioned His disciples to go “into all the world” and “teach all nations.” They were to leave none unwarned, but were to “preach the gospel to every creature.” Matthew 28:19; Mark 16:15. (AA 174.2) MC VC

In turning to the Gentiles in Antioch of Pisidia, Paul and Barnabas did not cease laboring for the Jews elsewhere, wherever there was a favorable opportunity to gain a hearing. Later, in Thessalonica, in Corinth, in Ephesus, and in other important centers, Paul and his companions in labor preached the gospel to both Jews and Gentiles. But their chief energies were henceforth directed toward the building up of the kingdom of God in heathen territory, among peoples who had but little or no knowledge of the true God and of His Son.
