Paul stood before the audience and commented, "I have toured your city and I see that you are a very religious people. I even saw an alter to "THE UNKNOWN GOD"...I am going to tell you about this "unknown God." You see, He is the God who made the world and everything in it. He is the Lord of heaven and earth. He does not live in temples made by human hands, nor is He served by human hands...as if He needed anything! He is the one that gives all men life and breath and everything else! He is the one that created man and from one man, nations were born. He determined the times set for them and the exact places where they should live. God did this so that men would perhaps reach out for Him and find Him - even though He not far from each one of us. For in Him we live and move and have our being. Some of your own poets have said, 'We are His offspring.'
Thus, since we are His offspring, we should not think that His divinity is like gold, silver, or stone - an image made by man. In the past, God overlooked such ignorance, but now He is calling us to repent. He has set a day for judgement when He will judge the world with justice by the man He has appointed. He has given proof of this by raising Him from the dead. (The man raised from the dead is Jesus Christ.)
When the audience heard this, some sneered - especially at the Resurrection of the dead, but some believed. Others wanted to hear more.
