The Signs of the Covenant Part 2 | Lord's Day Sermon | 17th August, 2025 | Adeola Ogundele
Description
In today’s sermon, The Signs of the Covenant, part of our Genesis series on Beginnings, Pastor Adeola Ogundele unpacks Genesis 17:9–14 to compare circumcision under the old covenant and baptism under the new covenant.
Circumcision was given to Abraham as a visible sign of belonging, pointing to purification and the need for a new heart. Yet in the old covenant, one could bear the sign without truly belonging to God’s family, as with Ishmael and Esau. God’s law remained outside of them.
In Christ, the old covenant signs have been fulfilled. Circumcision, temple sacrifices and priestly rituals were scaffolding that has now given way to the substance. The new covenant is marked by inward transformation through the Spirit. God now writes His law on our hearts, and you cannot belong to this covenant without belonging to His family.
The new covenant sign is baptism. Unlike circumcision, it does not mark national identity but personal faith. It declares our union with Christ, testifying to the inward change of new birth. The water itself does not save, but it points to the deeper reality of the profession of salvation.
This contrast warns us that outward signs must flow from inward faith, assuring us that we belong to Christ and live by His Spirit.
