Preterist believe that the kingdom is a here it is . . . there it is . . . They can not see that the kingdom does not come with observation. If it is not with observation, how can Jerusalem's fall be the point when the kingdom is made complete or is consumated in 70ad? The kingdom is eternal. It has no beginning nor does it ever end. The kingdom is also spiritual but Preterists seem to make the kingdom into a temporal period of time, subject to their assumptive system.
Sam Frost Article: Todd Dennis and Preteristic Idealism
Jesus announced that his kingdom, the one that was "near" and "at hand" and would "come" within that "generation" and was already making pre-parousaic preparations within his people, would be "like a mustard seed." Jerusalem's Fall would point to and mark the arrival of this kingdom on earth within God's people. But, the Fall was natural, and, naturally, was loud. The arrival of the kingdom was spiritual, and came with a still, small drop of a tiny mustard seed. You could hardly see its arrival. But, it would grow, and is growing, and will continue to grow so that "all the birds of the air" can come in and find rest among its branches.
