Pastor Rhode's teaching focuses on Genesis 15 through 17, emphasizing the Abrahamic covenant. He explains that Genesis 15 introduces the covenant with promises of Christ and the land. Genesis 16, featuring Sarai and Hagar, initially appears out of place but is interpreted by Paul as representing two covenants: Sarai symbolizes the Abrahamic covenant (the promise of Isaac) and Hagar symbolizes the Sinai covenant (the covenant of works). This interpretation is found in Galatians, which was discussed in the previous session. In the current session, Pastor Rhode examines Genesis 17 and its treatment in Romans 4, highlighting Paul's understanding of the Abrahamic covenant and its fulfillment in Christ.
