The prophecy relating to Zechariah 9:9 stated that the Messiah would enter Jersusalem riding a donkey... and that's exactly what happened. Jesus rode into Jersusalem on a simple little donkey, showing everyone around Him that he was there not to intimidate them and make them feel small, but to relate to them, and lead them to The Way. This prophecy helps me to know that Jesus is/was the Messiah and not a lunatic is because of what happened in the events afterwards. If Jesus were a lunatic, His actions and words would have followed suit after he became settled in Jerusalem. The people would have seem Him doing crazy things, or telling crazy stories, and he did none of that; he was perfectly sane in mind and body.
Isaiah 9:6-7/ As sovereign king
The prophecy relating to Isaiah 9:6-7 stated that a son would be born having the government on his shoulders, and be called, "Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace." God indeed has a government in Heaven ruled by Him both fairly and justly for all eternity. This prophecy tells me that God is not a lunatic because the facts just don't add up. Lunatics do things that are absurd and make no sense at all, so if God were a lunatic, why would He rule His kingdom righteously and fairly? Why would He want to love all people regardless of their race, or social status? Why would he want to help us get I the right oath so our lives can be happy and as stress free as possible? It just doesn't make sense, and there are many words to describe His actions, and crazy is definately not one of them.
Not a liar
Both of these prophecies let me know that Jesus was not a liar because I know that liar's are either mean, or they have a motive for their actions. Anyone, even non- believers can clearly see that Jesus was not a mean man, and all of Jesus' motives were for the good of others. He never sought out to do anything mean to anyone, and He never once tried to hurt someone, so His motives were purely good. To conclude, there is absolutely no solid, or believeable evidence that could be given without a fault to make Jesus seem like a liar or mad man.
