When God does a new thing, the old thing is supplanted. Thus, once Messiah came, the temple was rendered obsolete for God’s purposes. This is the way of God. This is how He works.
Therefore, when the church came into being, the nation of Israel was rendered obsolete for God’s purposes. And, similarly, when the kingdom of God came, the church was rendered obsolete for God’s purposes. Granted, the time frame of the church was much shorter than that of the nation Israel. It was approximately 1,500 years from the time God used Moses to form a bunch of slaves into an independent nation until the time of the church, but only one generation after that before the kingdom of God came. Nevertheless, the church became obsolete just as the nation of Israel had because the kingdom of God superseded it just as it had superseded Israel.
Nothing will supersede the kingdom of God, however, for we have been clearly told that it is eternal (Isaiah 9:6-7, Daniel 7:13-14, and elsewhere).
