Yes, but time was involved, the Son of God had to be born into the realm of time in order to suffer and die. Until that was done, there wasn't the type of propitiation that you are talking about. If it was, then all the O.T. sacrifices were for nothing. If the O.T. saints believed, then they were washed by Christ's "future" blood, and there wouldn't have been the need for all those bloody sacrifices. Doesn't add up to me.
