Ans.1. The term Messiah means "anointed one" and this person will literally be anointed. Daniel 9:24 "Seventy weeks are determined upon thy people...to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy". Elijah will also be anointed. Zechariah 4:14. All of the OT laws will be observed until the Messiah comes to Jerusalem and changes them. "Remember ye the law of Moses my servant, which I commanded unto him in Horeb for all Israel, with the statutes and judgments". Malachi 4:4. Jesus' covenant to Christians was belief only. They are caught in the grip of Satan.
2. The final prophet is the Messiah. The God of Israel is the first and the last, and scripture ends with the resurrection. This will mark the beginning of the final earth age and the heavens and earth will be renewed. If Muhammad was a prophet of the God of Abraham, why is there so much hatred between Muslims and Jews? Muslims pay lip service to the living God but they do not obey his laws. The Christians are no different. The coming Messiah is the savior of the Jews.
1. What are those "70 weeks" mentioned in Daniel 19:24? When they will start? Do you mean to say that "there will be a religious revolution" in the current Materialistic , atheist Ashkenazi controlled country of Isreal and they will start observing all laws of Torah?
(I think they will better prefer to go back to from where they came!!)
You are more believer in OT books than the people who wrote them!!
2. The Final Prophet has come and that happened 1400 years back.
If you are waiting for any New Messiah to come, that will be Anti Christ spoken in NT books.
It looks to me that you will be happy to follow that anti Christ than the real Messiah.
