Interestingly not all prophets in the Old Testament are Jewish - most notably the prophet Balaam in Numbers 22 - and some of the prophets are not sent to the Jews such as Jonah whose message is delivered to the Gentiles of Nineva.
Often prophets have a very rough time of it and are often not accepted by the people they are sent to (as Jesus says in Matthew 13.57 - "A prophet is not without honor except in his own town and in his own home."). Elijah was described by King Ahab as “the troubler of Israel” is never really listened to throughout his career. Jonah was swallowed and then spat out of a fish and forced to go to Nineveh where he did not want to go. Ezekiel was made to lie on his Left side for 390 days and then his right for 40 days - this was to make up for the rebellion of Jewish people! And Hosea was directed by God to marry a promiscuous woman, divorce her and when she has sold herself into slavery re-marry her - their children are given symbolic names such as “unloved” and “not my people”.
For Christians the culmination of all the Old Testament Prophecies was the birth of Jesus of Nazareth - the Messiah predicted by Isaiah in 9.6 as the “Wonderful,Counsellor, Mighty God, the Everlasting Father, the Prince of Peace”. That he would be born of a virgin by Jeremiah (31.22) and that he would be both God and Man (23.5-6). And finally that he would die for the sins of the world and by doing so put an end to sin and reconcile us with God (Daniel ch. 9). This is what Philip says in the Gospel of John, who told Nathanael, “We have found the one Moses wrote about in the Law, and about whom the prophets also wrote – Jesus of Nazareth, the son of Joseph” (John 1:45).
Obviously this claim needs the faith of belief in Christianity to be seen as true and many would deny them - Jews that they have yet to come about and Atheists that they are just wishful thinking. Either way the prophets represent a rich vein of Philosophical and Theological material that have inspired the generations and impacted upon our literature, music and culture.
How has our modern day culture been influenced by the Prophets of the Old Testament?
