My understanding (it's been a while) is slightly (but significantly) different, and you could chalk that up to theological differences.... But the way I understand it is, belief is sufficient on its own (Romans 10:9), and also, if you DO believe, you'll follow through (Luke 6:43-45). It's not so much "You have to do Christian-y things" (Ephesians 2:8-9) -- that's the symptom, not the salvation. It's not something you buy with good behavior, because you can't afford it. It's a gift you're given and grateful for and, if that's true, you're not wasting it on trivial bullshit.
You're not entirely wrong. I never said you need to earn your way to heaven. That's why I clarified with phrases such as '
Of course, since we are human, all of that is pretty much impossible. But to attempt to live in the faith, as much as you can, is something God wishes.' True belief merits action. One who does believe will acts accordingly.
John 14'15: If you love me, obey my commandments.
John 15'14 (lol): You are my friends if you obey me.
and the most important one
Luke 13'24: The door to heaven is narrow. Work hard to get in, because many will try to enter. But when the head of the house has locked the door, it will be too late. Then you will be standing outside knocking and pleading 'Lord, open the door for us!' But he will reply 'I do not know you.' You will say 'but we ate and drank with you, and you taught in our streets.' And he will reply 'I tell you, I don't know you. Go away, all you who do evil.'
Now, theologically, it is true to say that no amount of good works can 'buy' someone into heaven. Because Heaven is a perfect paradise and no man is perfect, therefore no one is ever worthy. However, to
not attempt to live a live of giving and kindness is also blasphemous. To put it simply:
If you love Jesus, you'll care about following him. If you care about following him, you'll do christ-like things. If you do christ-like things, you'd be a follower. Someone cannot say 'I love God and am a believer' and then regularly cheat on his wife, for instance.
Also always take Romans with a grain of salt. Not to say it is false, per say. However, Paul is not Jesus. Romans and the like is secondary compared to books like Luke.
