There have been various thread discussing Penal Substitution in the past.
On one of those, when we were discussing 2 Cor. 5:21-- 'For [God] made Him who knew no sin to be sin for us, that we might become the righteousness of God in Him'-- it was suggested that rather than Christ being made 'sin' (Gk. hamartia), He was made a 'sin offering.' I felt this was very unlikely because then the natural translation would be '.....Him who knew no sin offering to be a sin offering for us....' which is nonsense, but the person in question still felt he was right and the discussion faded away.
I was thinking today about John 3:14-15, and Moses lifting up the bronze or copper serpent in the wilderness in Numbers 21:8. Now the serpent is obviously a type of Christ-- but why is our Lord on the cross typified as a bronze (KJV 'fiery') serpent? Surely, if Christ were made a sin offering, He should be typified by a bull (Leviticus 4:4ff) or possibly by a goat (Leviticus 16:5ff)? No, the serpent is a figure of Satan and typifies Christ made sin. There on the cross, He was made the very epitome of sin. All our sins were laid to His charge and heaped upon His sinless shoulders, so that He could pay the penalty due and satisfy God's outraged justice, and His perfect righteousness and obedience credited to us who believe.
