Sac,
this sentence seems to be at the core of the quote you gave.
Paul is saying, if I interpret it correctly, that the nature of the world around us is the key reason for believing in God, and that what God is like is revealed by what he has created. Is that how you interpret it?
A lot has changed since 1st century AD. There is good reason now to believe that there are natural explanations for what exists, and there seems to be no need for the supernatural in any of it. So how can use we use this today as a way of evidencing God?
