The Abrahamic Covenant speaks of salvation by faith alone through God's promise to Abraham of descendants, land, and blessing all nations. The Mosaic Covenant given at Mount Sinai revealed mankind's inability to be righteous through the 613 laws and was meant to drive people to Christ. The Abrahamic Covenant is unconditional while the Mosaic Covenant was conditional, and both covenants point to Christ and the New Covenant of salvation through faith.
