Out of the 52 recorded narrative parables, 20 depict Jesus in imagery which the Old Testmanet typically refers to God
Jesus acted as if he was God:
Since Jesus claimed to be God, he can't be just a great moral teacher and not be God. He would not be a good teacher if he was a liar.
But being a liar does not match the facts. He would not have liad down unless he was telling the truth
Lunacy does not fit either; Jesus utter some of the most profound sayings ever recorded. Even His enemies claimed that Jesus was a man of integrity and taught the truth - Mark 12:14
We are left with only one conclusion, Jesus is Lord
