The Old Testament circumcision was of the flesh as an outward symbol of a covenant relationship with God. Our circumcision is of the spirit removing our sinful nature and replacing it with God’s Holy Spirit. Our hearts and desires were changed and God wrote His Name upon our hearts. Our baptism is the outward symbol of being buried with Christ and raised again to a new life.
” Put on your new nature, created to be like God—truly righteous and holy.” Eph. 4:24
We were spiritually dead in our sinful nature but now all things are made new. We are new creatures:
“Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life.”-Romans 6:4
