By now you probably have the Offertory essay. Any discussion? I received one question asking this: “If Jesus is the bloody firmament that protects all on the earth, how can the magistrate have the right to exercise the death penalty? Isn’t the criminal protected?”
My answer, part 1: The same is true in the Old Covenant, for the blood of the Day of Coverings covered the firmament temporarily.
My answer, part 2: God has given to the more mature human race (after the Flood) the right/duty to remove from the earth and sent up to Him certain kinds of criminals. These people are removed from the protection of the bloody firmament, and they had better be In Christ, not merely Under Christ, at the time of their death, else they will lose all grace.
