(CNN)Here is a look at Christianity, the most practiced religion in the world.
Followers of the Christian religion base their beliefs on the life, teachings and death of Jesus Christ.
Christians believe in one God that created heaven, earth and the universe.
The belief in one God originated with the Jewish religion.
Christians believe Jesus is the "Messiah" or savior of the world. They also believe that he is the son of God.
Jesus was born in a manger in Bethlehem to Mary, a virgin at the time of conception, and Joseph, her husband. Mary was visited by the angel Gabriel and told she would conceive a son and he would be the Messiah.
Jesus was crucified on a cross. His death made salvation and forgiveness of sins possible for all.
On the third day after his crucifixion, Jesus arose from the dead. His resurrection is celebrated on Easter, which is considered Christianity's most important holiday.
After Jesus' crucifixion and resurrection, God's presence remained on earth in the form of the Holy Spirit to be a comforter to all.
Salvation can only be obtained by believing that Jesus was sent by God to forgive the sins of every human, and to confess those sins to him.
Interpretations of the Bible and the practices of each church vary by denomination, but the belief in one God and Jesus as the Messiah is central to all Christians.
Christian beliefs date back thousands of years before Christ.
Many prophets predicted the coming of Christ, as written in multiple books of the Old Testament, according to Christian belief.
