Someone correct me if I am wrong, but for a Baptist, the seal of the New Covenant is the Holy Spirit, not baptism.
Actually, I think that Reformed Baptists believe the seal of the New Covenant is baptism. However, they believe that baptism is only to be administered to those who have a credible profession of faith, since only those with saving faith are true members of the New Covenant.
Please correct me if I'm wrong.
