Let me put it this way for you sir, If there is no God in any sense, what possible reason could you have for not killing yourself. A simple question, to which i am absolutely confident you cannot present me an answer.
Oh, indeed I DO have an answer.
I throw this back at you, because this type of argument pisses me off to no end as well. And I want you to think about this, because you have it exactly backwards.....
If you are an atheist, then you understand completely that this is the ONLY life we get. You understand that after you die, there is most likely nothingness. Existence ends right then and there. So the atheist has to come to terms with that and understand that something, is always better than nothing. An atheist lives their life knowing that this is all we KNOW we get. So we value it much more than any Christian ever could.
If you believe in God, however, then you believe you have another life after this one. And you know that the other life is going to be infinite and full of greatness with no pain, no death, no suffering. You have something to look forward to that is way better than this life, and all it takes is the stopping of your heart. So I ask you, WTF are you waiting for? Go out and kill yourself so you can get to that next life. This one is so full of terrible, awful, baby eating atheists, what keeps you here? What is your "purpose" for being here that supercedes God's ultimate purpose for you in the kingdom of heaven? Giving glory to God? So your purpose is to be a cheerleader for a fictitious supreme being? Nuts. Just nuts.
In life, the things atheists live for are real. Family, friends, love, entertainment, learning, and so much more. Do you find those to be bad reasons to choose life over death? Do you place no value on those things? Do you find those things not worth living for? The difference is that we choose to live our life without the belief in something for which there is no evidence. It seems to me, you are saying the only thing in this world that is actually worth living for is your God. Well, I hate to break this to you, but that's really, really sad.
So tell me again, why you think you have more to live for? My wife and kids should be home any minute from the gym. What better thing to live for than seeing them every day?
Your life on this earth is spent thinking you are doing something positive for a being that isn't real. It is all I can do not to laugh and point at you.
Your God awaits your arrival in heaven. Go and join him.
And BTW, the reason people turn to atheism is not because there is some sort of benefit from it. They do it because they found no reason to believe that any religion is real. They value TRUTH over dogma. Honesty over lies. Reason over blind faith. If you don't value truth, then you are free to stick with your religion and believe what you want. Atheism is not a sales pitch. It's not trying to recruit you. It's not flashy and it doesn't offer you a fake sky daddy that will take all your problems away. It offers truth, nothing more. It's just opening your eyes to see the world for what it really is. If you value truth, then take the steps to find out what that truth is. If you believe in God, you do not have truth right now. I promise you that. Open your mind to the possibility that you are wrong.
Your God is not real. The reason for the confidence is nothing more than a conclusion based on an honest exploration for the truth. It is the same confidence that one would get trying to prove 2 + 2 = 4. Every time you add 2 things to 2 more things, you get 4 things. It works every time. After you do it a bunch, and you always get 4, then you can be act confident that it's true. That is where the confidence comes from. It is this same exploration that leads to the conclusion that Zeus is not real, Thor is not real, Allah is not real, and all the others. You simply don't have the truth here. You are wrong. Sorry.
