psalm123

Here is a good video that may be of help when discussing some basic arguments for the existence of God. Here Dr. Craig goes through 3 or 4 basic arguments (there are many others) you can use when discussing the reasonableness of Christianity. How often had you had your faith attacked as being "a blind faith in a cloud god" or something to that affect?  It's important to be able to articulate reasons for your faith using logic and reason. Of course this is only one aspect of the faith but it is important to be able to defend your beliefs reasonably against an increasingly hostile anti-Christian atheist movement.

The reason I like posting Dr. Craig's work is that he can take complicated philosophical principles and articulate them in a way that almost anyone can follow. At the same time you don't lose too much depth of the content.

Protestant Philosopher Dr. Craig briefly points out the problem with logical positivism. I have run into this kind of thinking when dealing with hard core atheists who refuse to accept the truth of anything that cannot be empirically verified. It would behoove them to study David Hume and Immanueal Kant in order to help take this philosophy to it's logical end and see it's limitations. Empirical science alone does not hold all the answers and is only part of the bigger picture. Good science, good Philosophy, good Theology.... all play a role in understanding the whole picture.
