No matter what the Bible plainly says, and conscience approves, every generation has those who think they can live in continual, habitual sin and go to heaven when they die. Also, in every generation there are enough false preachers and teachers who will nurture that vain hope in unconverted people and seal their eternal doom. People are so foolish and easily deceived that we give the devil more credit than he's due. Deceiving people is so easy a child could do it, and that makes his job very easy.
