FFC: that question is the same as 'are all people at heart, good' and 'do all people want to be good'. The answer is of course, a yes.
Although, spirituality is about trying to figure out how to achieve this more quickly with fewer steps.
Elisa, that statement is wrong on so many levels it astounds me. I know you truly want to believe it but you'll not find it anywhere in the bible. According to the scriptures that have been provided for you it is just the opposite. All people are sinful at heart, hence the savior that was sent to take away the sins of the world. Sinners need a savior not people with good hearts.
