Didn't you read the verse? Baptism is the antitype.
1 Peter 3:21 also to which an antitype doth now save us -- baptism, (not a putting away of the filth of flesh, but the question of a good conscience in regard to God,) through the rising again of Jesus Christ,
Yes, baptism is the antitype which saves us.
See, that’s not hard to understand, is it?
