The New Covenant, a central theme in Christian theology, marks the fulfillment of God's redemptive plan for humanity. It is a covenant that transcends the limitations of the Old Covenant, instituted with the people of Israel through Moses, and offers salvation to all people, including the Gentiles. This wotk seeks to unpack the historical, theological, and scriptural significance of the New Covenant, particularly with respect to its implications for Gentiles, exploring how the shift from an ethnocentric view of salvation to a universal one unfolded through the ministry of Jesus Christ. The roots of the New Covenant are found in the Hebrew Scriptures, where God repeatedly promised a future time when He would make a new agreement with His people. In the Old Testament, the concept of covenant is integral to understanding the relationship between God and His chosen people, Israel. The first covenant, made with Abraham (Genesis 12:1-3), promised blessings not only for Abraham's descendants but also for the nations of the world. God said, "all peoples on earth will be blessed through you" (Genesis 12:3), pointing to a future time when the blessings would extend far beyond Israel. Later, the Mosaic Covenant, given through Moses at Sinai, established a more formal relationship between God and Israel, with laws and rituals that governed their worship and behavior. Yet, the Old Covenant, as vital as it was for Israel, was limited. It was never meant to be the final and ultimate fulfillment of God's promise to bless all nations. The Old Covenant pointed forward to something greater—the New Covenant.
