This passage is one of warning. However, the difficult question is "Who is it warning?" Much discussion has been given to this passage with a variety of interpretations. In the end it seems to be warning those who have been surrounded by Christians and the church yet at some point fall away because they are not saved. It is impossible from a human standpoint to bring someone back who has left the faith. Can a person like this be saved? With men this is impossible, but with God all things are possible.
