I am always baffled at being told that life without God means no meaning to life. It makes sense inside the bubble, but outside of it, there's just no logic to it.
I don't get a lot of things anyways. Maybe I don't want to be as easily distracted as people were in the Bible. Moses goes up the mountain to SEE God. He is leading people who have witnessed miracles which could make believers out of non-believers. (Odd that not a single Egyptian saw fit to go with him, but hey) Moses is up the mountain and what do his people do? They build an idol to worship. ...... ...... Okay..... you're the stupidest people EVER. You know God is ON the mountain, right there in the physical sense. You build a statue to worship instead. You're also probably the most boring people ever while we're at it.
I don't need to build anything to worship. I like my life how it is. Now, I went to the Adventist church and, in their eyes, everything is an idol. You drive too much? Your car is your idol. Watch too much hockey? Hockey is your idol. Too much sex? Actually, that never came up... Anywho, it's not accurate. Just because I spend time on the computer doesn't make it an idol. It makes it a part of my life and a useful part at that. It makes the same amount of sense as saying my friends are my idols if I hang out with them a lot. Now, I like some of my friends a lot, but I won't be worshipping them unless they win Lotto or something.
So, what is the meaning of life without God? Life is the meaning of life. I don't believe in an afterlife, so this is all I have. To my wife and kids, I have great importance, so that's meaning as well. I enjoy living. I don't identify with the idea I have to worship something to give me meaning. If there's any existence which sounds hollow, it's needing something external to give you meaning. "Without God, I'm nothing." I feel sad for you. "God is all, we're garbage compared to him." I have a higher view of humanity than that and refuse to believe that any non-Christians are garbage. I struggle with Edmonton Oiler fans being viewed as human, but that's how it is.
My meaning to this life is to enjoy my family, gain as much knowledge as I can in things I enjoy, play sports, stay in shape and live as long and fruitful a life as possible. Along the way, I treat people as equals and try to avoid controversy. Anything can happen in this life and we don't know where, when or how it will end. I am 36 and I have outlived some healthy people already, people who led God-fearing lives of chastity, non-smoking or drinking and all and they're gone? I am still here. I will enjoy the time I have and I know life has meaning. I see it every time I am with my family and every time I have a moment to enjoy a sunrise, sunset or a really great Rammstein song.
To me, it just seems really simple. Life has meaning from life itself. Mine doesn't require a deity of any sort.
