Jesus Christ is the eternal Son of God, who became human about 2000 years ago and lived in ancient Palestine. Jesus was born to a Jewish mother named Mary, and foster-father named Joseph, lived among the Jewish people, taught them about God, established a body of believers called the Church, and was put to death by crucifixion. Jesus conquered death by rising from the tomb in his own real body, appeared to many hundreds of people, and ascended into heaven.
Christians call Jesus Christ the Lord and Saviour, and they believe he is active in their lives today, and desires a relationship with each of us.
