How many years, approximately, did Jesus Christ live?
Approximately 37. As far as we can determine, He was born in 4 BC, based on the death of Herod the Great, the Jewish king who chased the Holy Family into Egypt and slaughtered the children in Bethlehem. He died, and rose, in 33 AD, which we can pinpoint pretty accurately from the dates of Passover, which depends on the new Moon.
