That's not fully true. I know poeple who "believe in God" but are not saved. To be saved you need to pray from your heart and ask Jesus to come into your heart, you need to know that Jesus died to save you from your sins. When you know in your heart that Jesus died for you and you accept then you are saved. That's when and only when your sins are forgiven.

It boggles and frightens me each time I am reminded that "people" actually still think like this in this day and age. I usually find the least "Christ like" people on earth are those proclaiming to be Christian. Last I checked judgements on morality were to be left to God. Who are you to pass judgement on anything?
