It is believed that when we die, our soul leave the body and begins the journey of the dead where judgement would take place. This journey is an individual journey done alone. If one qualifies, the individual is taken to the Kingdom of God, but if not qualified, the person goes to hell to face the reality of true pains that never ends.
