Recently in my church's Men's Bible study class we have been going over the concepts of Free Will vs Predestination. This is quite an interesting study and one that brings up many questions. The reason I mention this is that today I was reading a blog that I read regularly (Dilbert Blog) and I found a link to this article that is a non-Christian look at this concept. I had no clue this was something that was even looked at from a non-Christian perspective. One of the main arguments for predestination is that God knows all and knew from the beginning of time that we would make the decisions we were going to make, so I just find that others would even look at this concept kinda odd.
In our class one of the best explanations for this debate was a quote from a Baptist minister. My memory fails me but I believe it was something like "The Bible speaks of predestination and the Bible speaks of free will and I believe in the Bible". I recommend partaking of this study sometime in your own Bible study group if you haven't already.
In addition, I want to say I don't really agree with the article I linked. If you base your theories off this article people would not be able to be prosecuted for their crimes because they were predestined to do their crimes (hence my suggestion on a doing a Biblical study on this). Also the argument about neuroscience vs evolution in the 3rd paragraph from the bottom seems to be a really silly argument.
