Everyone has a god.  This god can be the true God or it can be something else that we put in the place of god – table tennis, work, family, money, girlfriend, hobbies, etc…  In our Bible passage, the apostle Paul was in the city of Athens.  This city had many idols.  Paul saw one idol that was titled – To the Unknown God.  He explained to the Athenians about the one and only and true God and what they must do to have a true relationship with God.
 
 
Acts 17:22-31
Then Paul stood in the midst of the Areopagus and said, “Men of Athens, I perceive that in all things you are very religious; 23 for as I was passing through and considering the objects of your worship, I even found an altar with this inscription:  TO THE UNKNOWN GOD.
Therefore, the One whom you worship without knowing, Him I proclaim to you: 24 “God, who made the world and everything in it, since He is Lord of heaven and earth, does not dwell in temples made with hands. 25 Nor is He worshiped with men’s hands, as though He needed anything, since He gives to all life, breath, and all things. 26 And He has made from one blood[c] every nation of men to dwell on all the face of the earth, and has determined their pre-appointed times and the boundaries of their dwellings, 27 so that they should seek the Lord, in the hope that they might grope for Him and find Him, though He is not far from each one of us; 28 for in Him we live and move and have our being, as also some of your own poets have said, ‘For we are also His offspring.’ 29 Therefore, since we are the offspring of God, we ought not to think that the Divine Nature is like gold or silver or stone, something shaped by art and man’s devising. 30 Truly, these times of ignorance God overlooked, but now commands all men everywhere to repent, 31 because He has appointed a day on which He will judge the world in righteousness by the Man whom He has ordained. He has given assurance of this to all by raising Him from the dead.”
