"Go ye therefore, and teach all nations,"

Christ's words on the mountainside were the announcement that His sacrifice in behalf of man was full and complete. The conditions of the atonement had been fulfilled; the work for which He came to this world had been accomplished. He was on His way to the throne of God, to be honored by angels, principalities, and powers. He had entered upon His mediatorial work. Clothed with boundless authority, He gave His commission to the disciples: "Go ye therefore, and teach all nations," "baptizing them into the name of the Father and of the Son and of the Holy Spirit: teaching them to observe all things whatsoever I commanded you: and lo, I am with you always, even unto the end of the world." Matt. 28:19, 20, R. V.

The Jewish people had been made the depositaries of sacred truth; but Pharisaism had made them the most exclusive, the most bigoted, of all the human race. Everything about the priests and rulers--their dress, customs, ceremonies, traditions--made them unfit to be the light of the world. They looked upon themselves, the Jewish nation, as the world. But Christ commissioned His disciples to proclaim a faith and worship that would have in it nothing of caste or country, a faith that would be adapted to all peoples, all nations, all classes of men.
