The Hebrew Scriptures told a lot about the Messiah.
According to OT prophecies the Messiah’s arrival would usher in the end of sin, the end of suffering, peace and tranquility, one creed and one religion, one kingdom and one king, the resurrection of the dead, the abolishment of idolatry and false prophets, the gathering of the ten tribes of Israel, the building of the future temple, etc. etc. etc.
But Jesus didn’t bring about any of these world changes.
So is Jesus a false Messiah? A false Christ?
Christians say that Jesus will perform all the Messianic world changes when he comes a second time.
But how can we have confidence that Jesus will perform with the second coming? What’s his performance record so far?
Has Jesus fulfilled any of the Messianic promises with his First Coming?
Did Jesus provide us with any prophecies for the benefit of mankind that he has fulfilled?
If you can’t positively answer these questions with substantial accomplishments that we can all see for ourselves, then perhaps you may have to reexamine your faith.
