Why was the promise of the Messiah repeated from generation to generation?

it was repeated from generation to generation but only started from moses to the Jews.

before moses, abrahams religion were told of a prophet/saviour that would guide thewm from slavery - who was moses.

moses told them of Jesus, who was the true messiah but the Jews that didnt accept him, stayed as Jews still wating for their messiah - the ones that did became christians.

Jesus told us about the anti chrsit, and when the anti christ does come, the Jews will think that's their messiah, and their want to build his temple where the current day al aqsa mosque is - that's why the hoo haa about al aqsa - cus that's where he will rule from - and they wanna get his temple ready for him.
