Acts 17:22-23

22Paul then stood up in the meeting of the Areopagus and said: “People of Athens! I see that in every way you are very religious.

23For as I walked around and looked carefully at your objects of worship, I even found an altar with this inscription: TO AN UNKNOWN GOD . So you are ignorant of the very thing you worship—and this is what I am going to proclaim to you.
