Like the passing of Noah’s ark through the waters of the flood, the crossing of the Red Sea was a type of baptism (1 Corinthians 10:1-2 and footnotes 14 through 23; Genesis 7:17-23 and footnote 17-1). The waters of the Red Sea were used by God to save His people and separate them from Pharaoh and Egypt. The children of Israel were saved through the Red Sea into the wilderness, a realm of resurrection and separation (Exodus 15:22 and footnote 1), where they were free from all bondage and slavery to fulfill God’s purpose by building the tabernacle as God’s dwelling place on earth. Likewise, through baptism the New Testament believers are saved from Satan and the world into a realm of resurrection (Romans 6:3-5) and separation (Acts 2:40-41), in which they are free to accomplish God’s purpose by building up the church as the dwelling place of God.
This marked the completion of the first stage of God’s complete salvation of His chosen people, a stage that included the Passover, the exodus from Egypt, and the crossing of the Red Sea. The Passover, typifying Christ with His redemption, was sufficient to save God’s people from God’s righteous judgment (Exodus 12:12-13). However, in order to be saved absolutely from the tyranny of Pharaoh and the enslavement in Egypt, the children of Israel needed the exodus and the crossing of the Red Sea. Likewise, after enjoying Christ’s redemption to be saved from God’s judgment, the New Testament believers need to leave the world and be baptized (cf. Mark 16:16a and footnote 1).
