Prophecy is the intervention of God's sovereign grace in testimony, in order to maintain His relationship with His people when they have failed in their responsibility to God in the position they held, so that their relationship with God in this position has been broken; and before God has established any new relationship by His own power in grace. The subjects of prophecy are, consequently, the following:—The dealings of God in government upon the earth, in the midst of Israel; the moral details of the conduct of the people which led to their sin; God's intervention, at the end, in grace, by the Messiah, to establish His people in assured blessing, by God's own power. Two things are connected with these leading subjects: the judgment of the nations, which was necessary for the establishment of Israel in their own land; and the rejection of Christ, by the Jews, at His first coming into this world. Finally, Israel had been the center and keystone of the system that was established after the judgment upon Noah's descendants for their pride at Babel. In this system the throne and temple of God at Jerusalem were:—the one, the seat of divine authority over all nations; and the other, the place where they should go up to worship Him who dwelt between the cherubim. Israel having failed in that obedience which was the condition of their blessing and the bond of the whole order recognized by God in the earth, another system of human supremacy is set up in the person of Nebuchadnezzar. Prophecy treats, therefore, of this unitary system also, and of its relationship with the people of God on the earth. Guilty of rebellion against God, and associated with Israel in the rejection of Christ, and at the close rising in revolt against Him, this power is associated with the Jews in the judgment, as being united with them in evil.
