Israel in Eschatology
The Christian understanding of the Old Testament is determined by the christocentric focus by which the New Testament writers interpreted the Hebrew Scriptures. Therefore it is essential for a Christian to discover the principles and procedures according to which Christ and His apostles understood and expounded the writings of Moses, the Psalms, and the Hebrew prophets. Otherwise he is in grave danger of reading the Old Testament prophecies in an unchristian way and hence of misinterpreting and distorting the biblical prophecies simply by not interpreting the Old Testament by the New Testament key. The Old Testament is no longer the last word on end-time prophecies since the Messiah of prophecy Himself has come as the last Word. The New Testament has been written as the ultimate norm for the fulfillment and interpretation of Israel’s prophecies. A Christian would deny his Christian faith and Lord if he reads the Old Testament as a closed entity, as the full and final message of God for Jews irrespective of the cross and resurrection of Jesus, the Messiah, and apart from the New Testament explanation of the Hebrew writings.
