The apostle Paul explains to the early church that the experience of the people of God in their deliverance from Egypt was a kind of baptism. I Cor 10:1-5 expounds proclaiming that “ all were baptized into Moses in the cloud and in the sea..” We have recognized in recent messages that baptism, in part, is a rite of covenant head affiliation. In a baptism event, there is a sharing of the experience of the covenant member with the person and work of their covenant representative - hence - “all who passed through the sea and all who were under the cloud” were covenantally bound to God's appointed deliverer, in this case, Moses. This experience of passing through the sea, recorded in Exodus 14, prefigures a later fulfillment of God's covenant people who experience a “passing through the sea” in baptism. Therefore the apostle declares in another epistle (Col 2:12) that believers have received the new covenant sign of inclusion “having been buried with Him in baptism”
Jesus Christ as the greater Moses is exalted as our covenant head/representative in baptism. How much greater to be baptized into Him in whom (9) “the whole fullness of deity dwells bodily”? Furthermore, our covenant head is “the head of all rule and authority”. The argument- in the full scope of scripture – as to the significance of baptism as a rite of covenant inclusion, is from the lesser to the greater. When we consider the implications of legitimate Christian baptism foreshadowed in the Exodus, we realize that we are partakers in the greater miracle!
