Phrase that question properly, but I agree that it is likely that people are believing that all one has to do is “be a good person,” to get to heaven.
If in the sense of “moralistic therapeutic deism,” those folks have slim to no hope (not presuming on God’s knowledge and intentions) getting into heaven.
A caveat is always the fact that one who believes in Jesus is one who believes sincerely and that His commands are God’s commands to be followed by one who is a believer in Him.
But the difference is that, not simply the actions that are “good” can get one into heaven on their own merits. That is not possible.
There's a sense in which that's true, if you infallibly define "good person" the way God defines it. >:-)
Most people in our culture think "good person" is the same as "nice person" and "love" is the same as "approval". I don't think those are God's definitions. I wonder how many of us -- if we could read about them in a total vacuum, not knowing the text or knowing the person, but from complete blissful ignorance -- would truly consider Jesus to be a "good person". He certainly wasn't always nice, nor always approving.
