Jesus Christ, also referred to as Jesus of Nazareth, is the son God and is the central figure of Christianity. Bible has two main divisions, Old Testament and New Testament. Old Testament keeps referring about a Savior who was to come to save us and the New Testament talks about the birth and works which confirmed the prophecies and references which were made in the Old Testament. Jesus Christ is the base of the New Testament. Christians hold Jesus (Jesus Christ) to be the awaited Messiah of the Old Testament and refer to him as Jesus Christ or simply as Christ or Jesus or Emmanuel.
Jesus was conceived by the Holy Spirit, born of a virgin, performed miracles, taught about salvation, spoke in parables to people, died sacrificially by crucifixion to achieve atonement, rose from the dead, and ascended into heaven, from which he will return in the end times. Jesus came to this world for us and our salvation He came to show the way for us to attain eternal life, which was not available in the Old Testament. This new experience of being in Jesus Christ is also called being Born Again.
