I guess it's a matter of perspective, one would argue that if you have 0 of something you have nothing hence you cannot have anything less, yet another could say that you can have -10 of something, and therefore you owe something

relatively speaking - and based on the Bible - Jesus teaching is supposed to be the most important thing in a Christian's life, hence Luke 14:26 saying one must hate their father and mother in order to get to Jesus - because His teaching is meant to be above human love (e.g. if your father is Hilter or Putin who go against Jesus teaching by causing suffering to others, then it is better to hate them than betray Jesus teaching)

when it comes to atheism, I understand it is a lack of belief, but at the same time there must be something that is the most important thing during your time in this world, I don't think belief in nothing is your most important thing right?

it can be something physical or someone's teaching, it doesn't really matter, there is always something that is the *most* important thing to people, and for many, that is what you believe in

doesn't have to be called religion or faith, what you perceive as important is what you believe in, and in the end of the day what defines your mentality, and state of mind, also defines your actions and therefore who you are - so the end result is the same as having a religion

I have heard it many times. Each time I think it is wrong. 

The question we should ask ourselves is what is 'belief'? Here is a common definition from a dictionary.

conviction of the truth of some statement or the reality of some being or phenomenon especially when based on examination of evidence

So, right off the bat, a belief is a STATEMENT OF TRUTH. When you believe in something, you think of it as true. When one says I am an atheist, they are stating there is NO GOD. That is not 'lack' of belief. That is a statement. A fact you are saying out loud. I can have a 'lack of belief' in unicorns, but I still don't believe they are real. It is MY BELIEF that unicorns are not real. That is a statement of what I believe is fact. Replace that with god, and there you go! You made the same type of statement. 

If you want to take a true neutral position, like a scientist would do. You would state that there is no evidence for God's existence or nonexistence. That is called agnosticism. 

In short, atheism is not the DEFAULT position. You are stating in the ground that there is NO GOD. The DEFAULT position is agnosticism. Therefore, if someone tells me, I don't know if there is or is not a god.

I consider that a lack of belief in ANYTHING. Not just gods, but how the world works. Whether you believe in god or not, it fundamentally changes the way you think of the world. 

For example. Where do morals come from? If you believe in god, you would say. 'God.' 
If you are an atheist, you say 'Morality is a social construct, and can change depending on what society deems acceptable at the time.'
An agnostic is someone who says, 'I don't know where morality comes from. Because I lack belief that they have a source.'

TLDR:

Agnosticism is the true 'lack of belief' that atheists claim they have. By claiming yourself as an atheist, you are stating there are NO gods. None. Just like how atheists like to claim there is 'no' evidence of god. I like to turn it around and say, 'You have no evidence that there is not one.' Either way, you are taking a stance. Which one do you believe in? Guess what? You took a stance.

Anyway, let us not derail the thread. This can be done elsewhere at another time. 

I think you're just getting into semantics here. If you want to go that route, you could say most people have thousands of belief systems going on at once, all the beliefs that an unlimited number of imaginary things don't exist. But that would be pointless and kind of silly. Usually, a belief means that the object of the belief actually exists to start with.

Agnosticism is not an alternative to atheism, it is parallel to it. Most people on the planet are agnostic, whether they believe in God or not. Few people go so far as to claim to have actual knowledge about the existence or non-existence of God. If you are intellectually honest, you cannot know either way.

Atheism is in fact the default position. No one is born with a belief in anything, these things are acquired as we grow up, start to understand things and are influenced by others around us. A baby can't even comprehend itself, let alone the concept of God. Some people pick up faith at some point in their lives, some never do. Some go in and out.

Atheism is not a lack of belief in anything. We believe all kinds of things, just like everybody else. We just differ in one specific question. And you are an atheist as well, when it comes to most of the gods and deities people have come up with on this planet. I just have one less God than you, we're not that different.

Where morals come from is a complicated question. I suppose it's something like a mix of our innate conscience, upbringing, social norms and the benefit of all, that sort of thing. If it comes from God, I have to wonder what kind of a person one would be if it turned out there was no God. Would they suddenly just become a monster because there would be no guidance from above? If that's the case, please remain religious for the sake of us all. And if the God of this world should happen to be an evil God, I suppose you would adopt his morality by that logic as well? Or do you actually have some agency in morality after all?

But yes, let's not derail this further. I will remove myself and not bother this group any longer. Thank you for the conversation, it's always interesting and we could go on forever.

Actually… I’ve got a question. Have any of you struggle with feelings of guilt associated with video games? For instance: I cannot play any M-rated video games nor do I feel comfortable engaging too often with video games without feeling a deep rooted sense of guilt. As though I worship an idol of this world.

I have a hard time logically explaining how video games could bring guilt. It is art. No different than movies or books. It only becomes an issue when it draws you away from your duties. For example, if you choose to play video games instead of praying, then there is a problem. But if you did all your prayers, video game playing has no issues. If anything, you deserve it! 

So I would classify excessive video game playing as under the Deadly Sin of Sloth. 

As for mature games, I don't feel anything with extreme violence. I don't think it is considered a sin anywhere. Sexual stuff makes sense, but unless you are playing the game specifically for that stuff, it shouldn't be too much of an issue. 

There’s a passage from the Bible that I think is important to remember when it comes to playing video games:

“There is nothing outside a person that by going into him can defile him, but the things that come out of a person are what defile him.“

-Mark 7:15

I know when Jesus said this, he was talking about how all food is clean, but one can make the argument that he can refer to all forms of consumption, including consumption of media (especially video games). So in a way playing video games by themselves do not defile a person. But the actions and words that comes from those games.
