There are so very many things that people claim to do on instruction from God, either directly or through the Holy Bible. When you hear someone spouting off about such as you are passing by...hell...ignore them. If they are talking directly to you about it tell them that lots of people think they are receiving instruction from beings that are non-existent. These people are called schizophrenic, psychopathic, pathological, AND plain fu*king crazy. Nothing like being disillusioned by the divine.
