The birth of Jesus remains the pinnacle event of human history. Our calendars are based on his birth. Countless people are killed every day because they call themselves Christians. Jesus's mere existence has been debated and fought over for the last two thousand years.
There is enough historical evidence that we must accept that Jesus was a real person... BUT...
Jesus then asks "who do you say I am?"Is he the Son of God? Was he just a good guy? Or was he a crazed lunatic?
