Jesus was crucified at age 33, which was a painful form of execution. He was nailed to the cross with large nails through his wrists and feet, which caused extreme suffering as he struggled to breathe and support his body weight. Jesus endured this for over 3 hours before dying from blood loss and organ failure, pouring water from his wounds instead of bleeding due to losing all of his blood volume. The document emphasizes that Jesus endured this execution and all the preceding abuse to atone for humanity's sins so that people could be saved through accepting him.
