It's all a part of the Gospel of Jesus Christ... to not see it's Divine continuance is to subject it to man's realm of understanding. Yes, one part is the fulfillment of another but that can be shown in other parts as well... We don't separate the antediluvian dispensation from the Abramic or the Mosaic. We see progressng light in the whole of the bible with it's climax in the cross. It spans from the beginning to the end... Jesus the Word, the Alpha and Omega not the Alpha and/or the Omega.
