Who benefits from the Abrahamic covenant?
All people, regardless of where they are in human history, benefit from the Abrahamic covenant, because through Abraham's singular seed the blessing would come to all the world. Scripture identifies that seed as Christ, and the promise runs through Isaac, not Ishmael.
Les explains that the promises were made to Abraham and his seed, singular, not to many seeds. That singular seed is Isaac, and the line continues through Isaac, Jacob, and the twelve sons, ultimately pointing to Christ. Not Ishmael, but Isaac, carried the promised seed. Because the covenant promised that through Abraham all the world would be blessed, every person in every era of human history benefits from it. Les also notes that the Muslim world disputes this, claiming the Old Testament is polluted and that Ishmael was the promised seed, but the Bible as the Word of God shows the seed came through Isaac.
