What about world peace - (Isaiah 2:4) - We certainly don't have world peace.

What about the third temple - (Ezekiel 37:26-28) - Third temple was not built in Jesus time, in fact it was destroyed in 70AD.

What about a universal knowledge of God - (Zechariah 14:9). - Self explanatory. So many religions all worshipping different gods, they certainly don't all accept the same God.
The bible states when this happens you won't have to teach someone about God because they will all know him. This would make witnessing pointless, because based on these three prophecies when they happen you would automatically know that it was the Messiah, no questions asked. The fact that people are still questioning Jesus proves he was not the Messiah.

Most Christians say Jesus will fulfil these at his second coming, but where in the Old Testament does it state the Messiah that was to come, would come twice?
EvangelistPA - All the 1200 prophecies you are referring to are basically snippets of verses taken out of hermaneutical context. The third temple was supposed to be build when the Messiah came, a third was not built, but the second was destroyed.
Tom W - Instead of saying my question is humerous, try answering it.
