God chose Israel to reveal His character to men. He desired them to be as wells of salvation in the world. To them were committed the oracles of heaven, the revelation of God’s will. In the early days of Israel the nations of the world, through corrupt practices, had lost the knowledge of God. They had once known Him; but because “they glorified Him not as God, neither were thankful; but became vain in their imaginations, ... their foolish heart was darkened.” Romans 1:21. Yet in His mercy God did not blot them out of existence. He purposed to give them an opportunity of again becoming acquainted with Him through His chosen people. Through the teachings of the sacrificial service, Christ was to be uplifted before all nations, and all who would look to Him should live. Christ was the foundation of the Jewish economy. The whole system of types and symbols was a compacted prophecy of the gospel, a presentation in which were bound up the promises of redemption. (AA 14.1) MC VC

But the people of Israel lost sight of their high privileges as God’s representatives. They forgot God and failed to fulfill their holy mission. The blessings they received brought no blessing to the world. All their advantages they appropriated for their own glorification. They shut themselves away from the world in order to escape temptation. The restrictions that God had placed upon their association with idolaters as a means of preventing them from conforming to the practices of the heathen, they used to build up a wall of separation between themselves and all other nations. They robbed God of the service He required of them, and they robbed their fellow men of religious guidance and a holy example. (AA 14.2) MC VC

The disciples were to go forth as Christ’s witnesses, to declare to the world what they had seen and heard of Him. Their office was the most important to which human beings had ever been called, second only to that of Christ Himself. They were to be workers together with God for the saving of men. As in the Old Testament the twelve patriarchs stood as representatives of Israel, so the twelve apostles stand as representatives of the gospel church. (AA 19.1) MC VC

During His earthly ministry Christ began to break down the partition wall between Jew and Gentile, and to preach salvation to all mankind. Though He was a Jew, He mingled freely with the Samaritans, setting at nought the Pharisaic customs of the Jews with regard to this despised people. He slept under their roofs, ate at their tables, and taught in their streets. (AA 19.2) MC VC

The Saviour longed to unfold to His disciples the truth regarding the breaking down of the “middle wall of partition” between Israel and the other nations—the truth that “the Gentiles should be fellow heirs” with the Jews and “partakers of His promise in Christ by the gospel.” Ephesians 2:14; 3:6. This truth was revealed in part at the time when He rewarded the faith of the centurion at Capernaum, and also when He preached the gospel to the inhabitants of Sychar. Still more plainly was it revealed on the occasion of His visit to Phoenicia, when He healed the daughter of the Canaanite woman. These experiences helped the disciples to understand that among those whom many regarded as unworthy of salvation, there were souls hungering for the light of truth. (AA 19.3) MC VC
