Why did the Christian messiah fail to fulfill the messianic prophecies?

The Messiah was to bring in the earthly kingdom of God. He came as a humble servant the first time. There are prophecies concerning the Messiah that do not discuss the warrior king aspect. He fulfills those prophecies. God. did not specify a time when he would assume the warrior king aspect. There is still the rest of time for that to. occur. God said he himself would take away the sins of the world. Since Jesus was God, the first advent was committed to fulfilling that prophecy.

They are wrong. Jesus did take away the sins of the world.18 And all things are of God, who hath reconciled us to himself by Jesus Christ, and hath given to us the ministry of reconciliation;19 To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them; and hath committed unto us the word of reconciliation.20 Now then we are ambassadors for Christ, as though God did beseech you by us: we pray you in Christ's stead, be ye reconciled to God.21 For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.Not all men are saved however. They have to reconcile with God. All they have to do is accept with Jesus did on their behalf. If they refuse, God's taking away all sins of the world does no good.
