God, from the very beginning, has been purposely heading toward a definite conclusion that includes the Gentiles within His covenant. The promise given to Abraham, that in him all the families of the earth shall be blessed, extends beyond the Israelitish people to encompass spiritual salvation through Jesus Christ. This promise, expanded into an everlasting covenant, reveals God's intent to include all nations who believe by faith, as Abraham did. Even in the early records of Exodus, God made it clear that the covenant is open to Gentiles, though the Israelitish people historically made little effort to convert them. This changed after Christ's resurrection, with vigorous efforts through the preaching of the Gospel directed toward Gentiles, as seen in the ministries of Peter and Paul, who was specifically called as the apostle to the Gentiles. Paul emphasizes in his writings that God had the Gentiles in mind from the start, alongside the Israelites. By faith, both Gentile and Israelite become one in Jesus Christ, united regardless of race or ethnicity, meeting the same requirement of believing God and activating faith. Gentiles, once far off from Israel, Christ, and the covenant, are now drawn near through God's calling, repentance, conversion, and the receiving of His Spirit. In God's eyes, they are no longer Gentiles but are fellow citizens with the saints in the household of God, a spiritual family and kingdom where God is the Father. This spiritual nation, distinct from the physical nation of Israel, is designated as the Israel of God. It consists of both Gentiles and Israelites who are part of God's family, united under Christ, who has become central to the worship of God, replacing the physical temple with His own presence as the means of access to the Father.

When Jesus Christ instituted the new Passover symbol, He declared, This is My blood of the new covenant, which is shed for many. Upon baptism and acceptance of Him as our Savior, we enter into that New Covenant. The covenant, confirmed by Christ during His earthly ministry of three and a half years, extends beyond those alive at that time. Another period of three and a half years will complete the confirming of the covenant, setting the stage for the salvation of all mankind, particularly Israel. During this final period, much like His initial ministry, the focus will be on preaching and preparing a remnant of Israel through rigorous and possibly violent means. At the conclusion, they will enter into the covenant. Jesus stated He would not drink the fruit of the vine, the symbol of His shed blood and the covenant, until He drinks it with His disciples in His Kingdom. This joyous occasion will align with the time when Israel will also partake of the cup of the New Covenant for the first time. The covenant will remain available throughout the Millennium and into the time of the Second Resurrection, with the effects of the Seventy Weeks enduring beyond their fulfillment.

Gentiles, being called into the church, share in the same salvation as the Israelitish people, a circumstance that was once entirely new. Their salvation hinges upon Israel's covenant relationship with God, as His promises were made to Abraham, Isaac, and Jacob, from whom the Israelites descended. Thus, the promises come first to the Israelites, but salvation is also offered to the Gentiles. The warning remains clear: now is the time of salvation, and Gentiles must take heed of their advantages without looking down in scornful pride at the unconverted. They must awaken to the fact that they can be replaced, for while the unconverted Israelites stumble, they are not doomed to an irreparable fall. God is bringing good to the Gentiles now, as their advantages are not inherent or earned but are possessed on the basis of His favor, just as they were to Jacob. If God spared not the natural branches, the Israelites, Gentiles must take heed lest He also spare not them. His kindness is given to them now, but positions can be reversed, and they too can become objects of His sternness. When the blindness of the unconverted is wiped away, God is prepared to graft them in during the Millennium and the Great White Throne Judgment, and the called are being prepared to help these people when their time comes. The reason some are accepted and others rejected is because God has willed it, teaching the importance of submitting to His work in forming and shaping His image in those He calls.
