Ignoring the Tanakh breaks the fundamental law of the harmony of the Old and New. The B'rit Hadashah does not repeat all the promises of the Tanakh because its writers and central characters presupposed the authenticity and accuracy of Moshe and the Prophets. Thus, in particular, the reason Yeshua did not spend time teaching that physical Israel would be living in the physical promised land in the last days was that He presupposed that all the Tanakh prophetic scriptures were valid and literally true. To ignore the Tanakh is also to misunderstand the way the New refers to the Old. The B'rit Hadashah makes a wider application of the same principles enunciated in the Tanakh, but never at the expense of the original meaning. The "spiritual" meaning is dependent on the "natural" because it flows from it. The B'rit Hadashah always speaks in terms of "even as, so also" rather than "instead of, now this".Thus with regard to Israel and the Church, the B'rit Hadashah teaches "even as" Israel, "so also" the Church, not "instead of" Israel, "now the Church". For example, "even as" G-d promised to deal with Israel in blessing and discipline, "so also" will He bless and discipline the Church. Spiritual fulfilment does not replace the natural, but hangs upon it, flows from it, and completes it. This is the meaning of the term "fulfil" when used by the New in relation to the Old.An example of this principle is seen in 1 Kefa 2:9 where Shaul is not saying that the Church has replaced Israel as the chosen race, royal priesthood or holy nation, but that "even as" Israel in the Tanakh was (and still is) chosen and called as G-d's special people to declare His glory (Sh'mot 19:5-6 etc), "so also" does the body of believers, the Church have a similar calling.
