I have to take issue with those who believe that all that is required is faith in Jesus. One of the most well known scriptures is John 3:16, which many bibles translate something like "For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life." However, a more accurate translation would be "For God loved the world so much that he gave his only-begotten Son, in order that everyone exercising faith in him might not be destroyed but have everlasting life"
There is a difference between having faith and exercising faith. Excercising implies some sort of action. The scriptures support this idea, such as James 2:14-17. "Of what benefit is it, my brothers, if a certain one says he has faith but he does not have works? That faith cannot save him, can it?*If a brother or a sister is in a naked state and lacking the food sufficient for the day,*yet a certain one of YOU says to them: “Go in peace, keep warm and well fed,” but YOU do not give them the necessities for [their] body, of what benefit is it?*Thus, too, faith, if it does not have works, is dead in itself."
That works must accompany faith is further supported in 1 Corinthians 2:24-26. One particularly interesting scripture showing that mere belief is not enough is at James 2:19. He makes the point that even the demons believe, but this obviously will not save them. It states that they shudder, well aware of their coming fate.
I guess I don't have too much of a point to this, just some interesting lunchtime Biblical food for thought.
