Most of Jesus's life is told through the four Gospels of the New Testament Bible, known as the Canonical gospels, written by Matthew, Mark, Luke and John. These are not biographies in the modern sense but accounts with allegorical intent. They are written to engender faith in Jesus as the Messiah and the incarnation of God, who came to teach, suffer and die for people’s sins.
Jesus was born circa 6 B.C. in Bethlehem. His mother, Mary, was a virgin who was betrothed to Joseph, a carpenter. Christians believe Jesus was born through Immaculate Conception. His lineage can be traced back to the house of David. According to the Gospel of Matthew (2:1), Jesus was born during the reign of Herod the Great, who upon hearing of his birth felt threatened and tried to kill Jesus by ordering all of Bethlehem’s male children under age two to be killed. But Joseph was warned by an angel and took Mary and the child to Egypt until Herod’s death, where upon he brought the family back and settled in the town of Nazareth, in Galilee.
There is very little written about Jesus's early life. The Gospel of Luke (2:41-52) recounts that a 12-year-old Jesus had accompanied his parents on a pilgrimage to Jerusalem and became separated. He was found several days later in a temple, discussing affairs with some of Jerusalem’s elders. Throughout the New Testament, there are trace references of Jesus working as a carpenter while a young adult. It is believed that he began his ministry at age 30 when he was baptized by John the Baptist, who upon seeing Jesus, declared him the Son of God.
After baptism, Jesus went into the Judean desert to fast and meditate for 40 days and nights. The Temptation of Christ is chronicled in the Gospels of Matthew, Mark and Luke (known as the Synoptic Gospels). The Devil appeared and tempted Jesus three times, once to turn stone to bread, once to cast himself off a mountain where angels would save him, and once to offer him all the kingdoms of the world. All three times, Jesus rejected the Devil's temptation and sent him off.
