However, these three persons are regarded as a unity, sharing one 'substance'. Christians believe that Jesus Christ is the Son of God, who came to earth as a man to restore the relationship between humans and God which had gone wrong. He was crucified as a criminal and was seen alive after he was dead and buried. Christians believe that during Jesus' life he had shown people how to be reconciled to God and to each other. Jesus' death and resurrection was a form of atonement for the actions of humans and restored them to their correct relationship with God.
Christians have only one life.

Whether 'heaven' and 'hell' literally exists is hotly debated in some theological circles. The Christian place of worship is called a Church. They are often built in the shape of a cross with the altar facing east towards the rising sun.
