I love how Stevens says "the age about to come" was to be eternal in 70ad by maintaining it was a post-70AD period. How can something become eternal in 70ad? What was eternal by a historical period of time? It is also funny to see how Stevens describes this "transition period" between the new and old as if it was a dispensational line tied to the year 70AD. What Stevens misses, is the transition from the Old to the New as one is born again in Christ. The old man of the flesh (which is what all old things symbolized) is transformed into the new man renewed by the Spirit (which is what all new things symbolize). This is the transition process which never ceases and is in fact the eternal thing which Stevens sadly defines as a historic period. This is what the exodus symbolizes. It symbolizes our transition from the old man to the new man. Of leaving bondage, and entering into the rest in Christ. That which dies in the wilderness, the unbelieving generation" is not the first century generation, but the generation who resides in the covenant of death, whose desire of the flesh over the desire for God.

That 40-year period between Pentecost and Holocaust was just a transition phase between “this age” and “the age about to come.” It is “the age about to come” that was to be the eternal one. We have several examples of 40-year transitional periods in the OT (wilderness wandering, David’s reign, etc.). According to Moses and the prophets the transition between the two ages was not supposed to be eternal, nor even a long protracted period. Gentry has missed the significance of the transition period, and confused the passages about the transition period with those about the eternal kingdom.
