The central tenet of Christianity is the belief in Jesus as the Son of God and the Messiah (Christ). Christians believe that Jesus, as the Messiah, was anointed by God as savior of humanity, and hold that Jesus' coming was the fulfillment of messianic prophecies of the Old Testament. The Christian concept of the Messiah differs significantly from the contemporary Jewish concept. The core Christian belief is that through belief in and acceptance of the death and resurrection of Jesus, sinful humans can be reconciled to God and thereby are offered salvation and the promise of eternal life.While there have been many theological disputes over the nature of Jesus over the earliest centuries of Christian history, Christians generally believe that Jesus is God incarnate and "true God and true man"(or both fully divine and fully human).Jesus, having become fully human, suffered the pains and temptations of a mortal man, but did not sin. As fully God, he rose to life again. According to the Bible, "God raised him from the dead", he ascended to heaven, is "seated at the right hand of the Father" and will ultimately return to fulfill the rest of Messianic prophecy such as the Resurrection of the dead, the Last Judgment and final establishment of the Kingdom of God.According to the canonical gospels of Matthew and Luke, Jesus was conceived by the Holy Spirit and born from the Virgin Mary. Little of Jesus' childhood is recorded in the canonical Gospels, however infancy Gospels were popular in antiquity. In comparison, his adulthood, especially the week before his death, is well documented in the Gospels contained within the New Testament, because that part of his life was believed to be most important. The Biblical accounts of Jesus' ministry include: his baptism, miracles, preaching, teaching, and deeds.
