The Children of Israel knew that a Messiah would come to them. They had plenty of guidance in their scriptures to warn them yet when he came they(the religious authorities) did not recognise or accept him.
This was because they had developed their own idea of what he would be like and what he would do. They challenged Jesus to fulfill their own concept of Messiah and refused to believe him when he did not come up to their expectations. This has always been the way. Misunderstanding creates a block to acceptance.
This has happened repeatedly. Jews, Christians and Muslims have each their own concept of what the Messiah, predicted by each religion, would be like and would do; a misinterpreted concept. Hence they could not recognise him when he came. If they had done so there would be only one religion for they all taught the same thing.
The ways of God do not change. He sends men to guide men, men known and accepted for their high moral qualities, respected by their communities UNTIL they begin to claim to be prophets appointed to guide to the truth. THEN their communities reject them and their message until slowly the truth begins to be recognised and the number of 'believers' increases. Each community taking many years to develop into a world changing group.
Do not expect anything different from this repeated pattern or you may miss the real Messiah.
