These claims by Jesus in His own works, as noted typically in multiple accounts, follow from his claims of who He is
1 Eyewitnesses were estimated from the text description. Similar to the previous table, these events were documented during witnesses lifetimes, and these witnesses were willing to be tortured and killed for their testimony without any apparent recanting of that testimony.
Jesus continued to allow Jewish leaders to mistakenly think he was not born in Bethlehem as Micah predicted (they thought he was born in Nazareth) and purposely did not point out that Daniel predicted the year of his birth, or that Isaiah predicted a suffering messiah who would suffer for us as the "lamb of God". Jesus' primary purpose was not to be taken to become an earthly king. Jesus was God as judge who changed his clothes, came down to Earth as a man and paid our penalty for us.
I often hear people say, when hearing about a suffering savior, "That is not fair!" However, would you die for your children if it was the only way they could be saved? God is not subject to our limited human logic. His ways are higher than ours. This is a God of love and mercy who calls us to come to him up until the point of our death.
The point of this entire section can be summarized as: The evidence by fulfilled prophecies about HIm, fulfilled phophecies He offered, the great breath of miracles including raising others and himself from death after predicting that He would do so, in front of multiple eyewitnesses who did not recant under penatly of death makes a very strong case that Jesus was truly God in human form and thus his statements about himself are not likely those of a liar or lunatic, and certainly not a good teacher alone.
