A careful researcher must note that there is evidence that Jesus’s mother was a slave, and that Jesus was therefore born into slavery and He was a slave until the age of thirty. Slavery was ubiquitous in the time and place where Jesus lived, and this evidence so strongly fits the details of Jesus’s life that I have come to accept it as likely true. But for many, the very idea is so repellent that I leave it up to you to decide. Here is some of the evidence:
We all plan our lives on earth. And so did Jesus. He planned a life as the poorest of the poor, and in that time and place that may well have meant that Jesus chose to be born a slave so He could better observe and understand how people in that condition were treated by those above them in rank. And God could then have influenced the Emperor Augustus to decree the necessary emancipation in time for Jesus to begin His teaching career when He was thirty. Who knows?
