The biggest problem with your posts in these threads is that you make up stuff out of the blue. For instance, your definition of sin.
So here's a starting point, step away from this thread and actually do research on Christianity and other religions etc. Look up Christian doctrine and make sure you really understand it. If you have a question about Christianity or anything that's been really bugging you, Google it, and try do some research on it. See what others say and try to make a conclusion.
I haven't responded to your posts in a while, but I remember constantly trying to correct your misconceptions and wrong info in the threads that you post in and start.
I'm not trying to say this to be mean. All I'm saying is, it's hard to argue with someone when they're arguing against something that they don't completely understand.
