i've actually seen non-christians be terrified of the possibility of doomsday. the dates that are predicted, the movies etc in my experience it is the christians that are least nervous or anxious about it . they may find it intriguing or have a concern about their own ability to meet the potential challenges they face in terms of being a good and faithful witness but beneath all that they have a calm assurance that no matter what actually takes place in their own experience with this that they will be successfully carried through it by the loving hands of Jesus.
