God's ultimate aim is to bring people to spiritual salvation, which includes the restoration and renewal of the old along the path to a new creation. In the years following Christ's return, God will undertake the prophesied work of regathering and restoring Israel, demonstrating His role as a master delegator by sharing responsibilities and rewards with others. This restoration process adds value to Israel, introducing something new and of great worth that was not present before. By regathering, God will search the lands of Israel's enemies to find and return scattered Israelites to the Land of Promise, as foretold by Isaiah and Jeremiah. Isaiah 11:11 states that the Lord will set His hand a second time to recover the remnant of His people from Assyria and Egypt. Jeremiah 16:14-15 declares that the Lord will bring them back from the north and all lands where He had driven them, into the land given to their fathers. Restoration, on the other hand, involves actions to bring Israel back into God's favor, including returning them to prominence among nations. This restoration encompasses a single act of forgiveness on the Day of Atonement, as mentioned in Zechariah 3:9, and a gradual process of increasing wealth and prestige, as described in Isaiah 60:10-11. In Jeremiah 30, during the time of Jacob's trouble, God promises to bring back from captivity His people Israel and Judah, returning them to the land of their fathers. Jeremiah 30:3 affirms that the days are coming when God will cause them to possess it again. Further, in Jeremiah 30:8-9, God vows to break the yoke of oppression from their necks, ensuring they serve the Lord their God and David their king, whom He will raise up for them. This restoration is set in the context of God's determined purpose to regather and restore national Israel in the latter days. Ezekiel 37:21-22 reveals God's plan to gather the children of Israel from among the nations and make them one nation in the land, no longer divided into two kingdoms. Ezekiel 37:24 states that David, God's servant, shall be king over them, and they shall have one shepherd, walking in His judgments and observing His statutes. Moreover, Ezekiel 37:26-27 promises a covenant of peace, an everlasting covenant, with God's sanctuary set in their midst forevermore, affirming that He will be their God, and they shall be His people. This restoration includes a profound transformation, as Ezekiel 36:26-27 describes God giving Israel a new heart and a new spirit, removing the heart of stone and putting His Spirit within them to enable obedience to His statutes. This addition of the Holy Spirit ensures that Israel will never again backslide, securing their faithfulness under the New Covenant, a covenant of peace that will remain, as stated in Isaiah 54:10. Through these actions, God positions Israel for a significant role in carrying out His will worldwide.

In Isaiah the remnant of Israel and the dispersed of Judah are gathered from the nations. The envy of Ephraim departs and the enmities of Judah are cut off. Ephraim does not envy Judah and Judah does not harass Ephraim. In Ezekiel two sticks are taken one for Judah and the children of Israel his companions and one for Joseph the stick of Ephraim and all the house of Israel his companions. The sticks are joined into one stick and they become one in the hand. The children of Israel are taken from among the nations and gathered from every side. They are brought into their own land and made one nation in the land on the mountains of Israel. One king is king over them all. They are no longer two nations and they are never divided into two kingdoms again. They do not defile themselves anymore with their idols or with their detestable things or with any of their transgressions. They are delivered from all their dwelling places in which they have sinned and are cleansed. David the servant is king over them and they have one shepherd. They walk in the judgments and observe the statutes and do them. They dwell in the land given to Jacob the servant where the fathers dwelt. They dwell there they their children and their children's children forever. David the servant is their prince forever. A covenant of peace is made with them an everlasting covenant. They are established and multiplied. The sanctuary is set in their midst forever. The tabernacle is with them. The nations know that the Lord sanctifies Israel when the sanctuary is in their midst forever.

After the captivity and scattering of Israel, the tribulation of Jacob's Trouble, God's intervention on behalf of the remnant, and the Second Exodus, the reunification of Israel and Judah takes place as part of the restoration of the covenant people to the Promised Land. This reunification follows the sounding of the great trumpet that signals deliverance and the return of Jesus Christ, who gathers the elect from the four winds. At that time God breaks the yoke of foreign bondage from Israel's neck, saves the people from afar, grants them rest and quiet, and corrects them in justice without making a complete end of them. He demonstrates both justice and mercy by holding the nation accountable for its sins yet refusing to annihilate it as He did Sodom and Gomorrah, acting instead for the sake of His holy name and the promises made to the patriarchs. Once chastened, Israel and Judah receive perfect leadership under Jesus Christ as King and David as His prince, together with the resurrected apostles who judge the twelve tribes. They also enter the New Covenant, receiving the Holy Spirit that enables them to keep the law in its spiritual intent and to know their God with a new heart. Under these conditions the land produces abundantly, enemies are destroyed, the remnant multiplies, and the people enjoy lasting peace and prosperity. The survivors of the sword find grace, are led back with weeping and supplications, and are rebuilt as a people who once again recognize themselves as God's own. At that point the Lord declares Himself the God of all the families of Israel, and they become His people in a restored relationship marked by thanksgiving, joy, and security.
