It seems to me that so much of modern evangelical doctrine does not properly address and consider this all important audience relevance. This generation, the generation alive in the first century, the generation that had gained adult status during the ministry of Jesus is the audience that is being addressed. The old folks during this time might say that they would perhaps not live to see the fulfillment but, surely the young adults would. It was expected that they would view the fulfillment of all things; the passing of the one covenant and, the complete installation of the New Covenant; the end of the age and, the dawn of the age to come. This is what was considered to be the case when one looks at audience relevance and, there can be no other conclusion.
Personally, I think that the book of Hebrews sheds great light on the passing of the old covenant and the installation of the New.
The focal point for this event is the destruction of the temple. The tabernacle/temple of the Old Covenant was a pattern for the temple of the New Covenant. The New Covenant temple would not be a stone and mortar building. The New Covenant temple would be made up of living stones that would actually be the arc of the covenant, the dwelling place of the Holy Spirit and the place whereby God would dwell with men forever. After all the purpose of the tabernacle was stated clearly in Exo 25:8 And let them make Me a sanctuary, that I may dwell among them. The purpose of the Old Covenant and the tabernacle/temple was to foreshadow God’s desire to indwell humanity. In subsequent posts we will look at how Jesus then became the tabernacle/temple of God while here on earth and, how he merely became the firstborn of a living temple for God to dwell in on the earth.
