"(Now all the Athenians and the strangers visiting there used to spend their time in nothing other than telling or hearing something new.)  And Paul stood in the midst of the Areopagas and said, 'Men of Athens, I observe that you are very religious in all respects.  For while I was passing through and examining the objects of your worship, I also found an altar with this inscription, "TO THE UNKNOWN GOD."  What therefore you worship in ignorance, this I proclaim to you.  The God who made the world and all things in it, since He is Lord of heaven and earth, does not dwell in temples made with hands; neither is He served by human hands, as though He needed anything, since He hiself gives to all life and breath and all things; and he made from one, every nation of mankind to live on all the face of the earth, having determined their appointed times, and the boundaries of their habitation, that they should seek God, if perhaps they might grope for Him and find Him, though He is not far from each one of us; for in Him we live and move and exist, as even some of your own poets have said, 'For we also are His offspring.'"

The Athenians had a custom of following whatever was new.  They loved the fresh, the exciting life of discovery. 

But there is a problem with only loving what is new, and that is the temporary nature of newness.

So Paul flips their belief structure on its head.

Paul tells them about the living God.  Living, as in 'has always been, but is still new every day.'

Paul says, this is the God that you have missed almost completely. 

Are we missing the living God?  Who was and is and is to come.
