Yes, this is the main point of contention I have with this interpretation of scripture: the fact that their god is said to accept suffering as some sort of transactionable goods.
The question is why has somebody to suffer in the first place and what do I gain if some other person suffers in the place of the real culprit.
I mean it just doesn't make sense, especially if this god is omniscient and omnipotent.
Amen. Certain conceptions of God do not stand up to scrutiny under the cold light of logic. This does not mean God does not exist; it simply means man's view of the Almighty is severely flawed and colored by his own expectations, wants and desires.
