Rockpebblestone I think the wrathfulness of God and his attitude to humanity is not ignoring the subject, it is in fact very important to the question. Because the bible gives an insight in to the nature of god. The OP wants to know why if Jesus atoned for our sins why we need to be good. And to me the bible says basically we do need too follow gods rule and shows horrible consequences if they you do. If we do not understand god and his rules how can we answer the question?
Rockpebblestone its clear we disagree on the criteria for heaven and the numbers that will pass goods rules. I think the bible is pretty clear on this. But I also understand that it would be hard to follow such a horrible god. Of course you say there is scripture that supports your less restrictive entrance policy so also a valid argument. But does this not prove how erroneous and conflicting the bible is? Also my view of gods message is quite clearly and frankly put across in a few books of the bible. Is the scripture you get your more inclusive view from as numerous and as clearly put as the conflicting scripture? I place the importance on scripture because I believe it is the best source to answer the question. It is our only real set of instructions and guide to god.
ChristmasPeace you god is totally immoral. My objection is not to judgement or justice; its the total lack of justice and poor judgement of god. For example:
a. he has given us fair warning, really? So say I was born in the most remote part of the jungle, never hearing or seeing the outside world. Never hearing good word. Living a life that is not to harmful but totally sinful in terms of the bible. Maybe I had 3 wives, I have made numerous idols of false gods I was brought up with and praised them, never kept the Sabeth because I no not of it and so on. Not that the sin is that important as the magic key is accepting god in the first place. Anyway I was to die tragically you would understand me being a little upset if I was to come up to find this god that I never knew existed and them sent down for an eternality of horrible painful torment in hell? You would be like hey man you could have given me some warning!
b. We judge each other and often have legal frame works. These vary in fairness depending on cultural expectations and parts of the world. Most systems at least try to write some sort of proportionality into their sentencing structure, not god. He is very inflexible on this matter. You either except him as lord no matter how evil you have been on earth and go to heaven. Or you don't except him and face an eternity in pain and misery. Even if you have not been a very good persons that seems a little harsh don't you think? I mean an eternity of never ending pain and misery. That easily a million times worse than the death penalty. And in most places around the world they try to carry of the death penalty in a quick and as pain free as possible manner. Definitely not something that is drawn out in pain over an eternity.
Ok so we see god punishing the truly wicked. Lest see what he does eh? So 'God brought judgement it was at a time people had turned to idols, and were busy sacrificing their babies to the idols'. So he looks down and says that's bang out of order, fair play. So naturally he decides that mass genocide would show them a lesson, it sure did. Killing innocents. Once killing the whole planet and ironically all the innocent babies and animals bar two of every type. Does that sound like fair justice? Of course I suppose the population of the plant that was cleansed by god are still enjoying an eternity in pain.
Let look at the story of Sodom and Gomorrah? So the whole male population wants to rape the two angles that god set down. Understandably this is horrible and god is fairly upset. So how does god deal with it justly? Of course 'then the Lord rained down burning sulfur on Sodom and Gomorrah—from the Lord out of the heavens. Thus he overthrew those cities and the entire plain, destroying all those living in the cities—and also the vegetation in the land' (Genesis 19). So he slaughters all the bad men, the innocent women, children, toddlers and babies. Then just to add salt to the wounds he saves Job (the good guy) but his wife gets turns into salt because she disobeys god and looks at its destruction. And now the wicked heathen men, women and children of that land are spending eternity in pain and suffering. Was this slaughter just and proportional?
So is god just? No.
I would be a horrible concept to think that such a wicked and unjust person was in reality 'the judge and ruler, he has the ultimate authority'.
Lets hope not eh?
