Do I think every sin is equally bad? Actually I do. I know that sounds totally crazy but in God's eyes a sin is a sin and any sin however "small" in our eyes, is enough to separate us from Him. Does that mean that the consequences for all sins are the same? No. This is where we, as humans, start grading them on a scale. Some sins do way more damage to ourselves and others, so in that way it seems that some sins are much worse. But in the big picture, all sin is what keeps us apart from God. This is why a person who was a super amazing good person and did everything right their entire lives still cannot earn their way to heaven- All have sinned and everyone needs forgiveness for that sin.
And that is why the Christian god is a petty asshole and a spoiled little bitch. If someone does some minor bad thing to me, like lies, steals some change, or breaks something of mine and doesn't tell me, it's bad and it sucks, but I can forgive and forget, and still be their friend after some period of being a bit upset with them. Unlike that asshole god, I don't "separate myself from them" for every minor insignificant thing. Also, if they do something really bad to me, as opposed to a minor harm, I actually have the intellectual capacity to differentiate the two and know how bad one is compared to the other. God treating everything equally, and making the worst punishment possible for any crime regardless now minor, makes him sound really really evil.
Actually, there's a website I have been reading recently that talks about life and punishments in North Korea. Really horrific stuff, especially with their WW2 style concentration camps
http://freekorea.us/camps/ You should check it out. Your description of sin and god really reminded me of that, since the punishment for major crimes like theft and assault, and the punishment for minor crimes like thinking badly of Dear Leader or complaining about the lack of food, is punished equally, with being sent to one of their concentration camps (a real hell on earth) where people are constantly starving, forced to work all day, die constantly of all kinds of ailments or starvation, are beaten, tortured, and abused, and can even be shot for picking up chestnuts of the ground. All "sins" are punished equally with that hell.
You haven't seen followers of Satan doing evil? Basically it is pretty simple. There is good and evil. God is good, He is love. If we are not for God, we are against God.
Even if we don't acknowledge god or know or ever heard of him? Also this sounds like a "No True Scotsman" fallacy. But no, I have not seen anyone who actively proclaims to worship or follow Satan doing evil.
All rapists, murderers, child abusers, lairs, thieves and so on are serving Satan when they make evil choices and decide to do these sinful choices. So anyone doing evil is serving Satan
Your claim is that regardless of what the person believes, if they are doing good they are serving god, and if they are doing bad they are serving satan. That is false because people who don't know about or acknowledge either of those entities are not doing their actions to
serve someone else. They are doing it to serve themselves, the person they are doing the action for, or some other person or entity. At most you could claim that they are doing what god or satan would want then to do, NOT that they are serving them by their actions. E.g. if I give money to a homeless person, I am serving the homeless person and my own feeling of empathy, NOT god, even if I may be doing what your god might want me to.
On the flip side, are there people out there doing "good" and "loving" without knowing they are in reality unknowingly doing what God wants? Yes. And many of these same people also end up having very blessed lives because of that!
But then, once they die, even if god presents himself to them as undeniable proof, and they go, "Huh, you ARE real. Oops! Please forgive us for doubting your existence!" god still says "Nope! You should have believed in random crazy stories without any evidence! So now, despite you living very good lives as very good people, I will send you to a place where you will be tortured for eternity. Bye now!"
Instead of thanking Him for it, many of us just ignore Him, are angry at Him, or even deny He is the one giving us all the blessings we have.
Because a lot of us work very hard to achieve those blessings ourselves. A farmer that spends months working the ground, growing seeds, fighting off insects and infections, watering plants during droughts and digging ditches to direct away downpoor floods, should thank his own hard work for the "blessing" of food on the table, not god.
I believe the Spirit of God is present all around us. This is why throughout the world there are people that have a conscience and realize that some things are just wrong. There is a universal belief among most cultures that murder, abuse, adultery, stealing and lying is not a good thing to do and It doesn't matter what nationality, race or religion you are.
Actually it's evolution and genetics, not god. We survive better as a species, and are "fittest" to survive when we work together in packs as social animals. Survival of the fittest means social packs and groups, not just individuals. And this empathy and care for others has helped us propagate our genes better than those who tried to be individual and didn't work together or care for each other. Same as a school of small fish can survive as a species much better than if they were floating around as individual food bites. Best evidence of this, BTW, is that with time we have learned to have even more compassion, understanding, and are more ethical, than the people who wrote the bible 2000+ years ago. Many things presented as moral and ethical in that book are considered abhorrent now. Even the way god acts.
If a person truly wants to do what is right in their hearts God is fair and just and will give that person a chance to accept or reject Him I believe.
It's still INCREDIBLY petty and monstrously cruel that your god judges the entirety of a person's existence not of whether they were a good person, but whether they believe in him without him giving them any evidence to.
