Christianity or any religion for that matter that requires you to dedicate your life to it is not worth it. Saying for sure that any one religion is correct is almost pointless because depending on how you were raised, your beliefs that you are even exposed to changes. People brought up to believe that Christianity is correct has the same sted fast beliefs in their religion as a Muslim brought up to believe that Christians should all die. Just as Christians believe it is ok to make people's eternal souls burn in hell forever, a Muslim believe it is ok to kill Christians because the world must be rid of "infidels." I ask why would anyone dedicate their life to worshiping something that is really just about a 1 in 200 chance that it is correct. No one can prove where religion began but people will blindly vow to follow them. It is very possible to live a good life with good morals and good intent without saying you are doing it for a deity. Don't give god credit for things that YOU accomplish. When you sit down to eat don't thank god for putting food on the table. He did not put it there. You put it there because you got your own job on your own terms and went to the store bought your food and made it. I find it funny that people have to say they are who they are because of god or their religion because really they are who they are because of their morals and the values they hold to be important in life. Many people from many backgrounds have many of the same core values and beliefs but they will never be able to enjoy each others company because people aren't willing to talk to people of different religions openly. This world has gotten very shallow.
It is interesting that you argue against people who believe in religion for their irrationalities and their hostility towards different beliefs. You seem to imply that religion makes the world shallow (correct me if I'm wrong). The problem is not religion; its people who refuse to critically engage their world. This goes far beyond religion. For example, you maintain individualism:
"Don't give god credit for things that YOU accomplish. When you sit down to eat don't thank god for putting food on the table. He did not put it there. You put it there because you got your own job on your own terms and went to the store bought your food and made it."
Before I go further, I would recommend that you create an explicit straightforward argument. What is your conclusion? Religion is not worth following? Religion makes the world shallow?
