Christianity is a major world religion with over 2 billion followers that is based on the life and teachings of Jesus Christ. Jesus taught about God and living a righteous life in order to gain eternal life after death. However, he was crucified for his teachings which Christians believe was followed by his resurrection three days later. This event is central to Christianity's promise of eternal life for believers. Christianity has also generated a culture and set of beliefs that have been passed down for generations regarding practices, ideas, and faith in Jesus.
