There is only one "bridge" between faith and unbelief...the preaching of the gospel.
One man plants, another waters , another reaps the harvest.
Paul does not start with a "quote Moses" to the pagans on Mars Hill. He builds a bridge. He finds something they as pagans can relate to.
Notice in Acts 17:22 So Paul stood in the midst of the Areopagus and said, “Men of Athens, I see that you are very religious in all respects. 23 For while I was passing through and examining the objects of your worship, I also found an altar with this inscription,
‘TO AN UNKNOWN GOD.’ Therefore, what you worship in ignorance, this I proclaim to you. 24
The God who made the world and everything that is in it, since He is Lord of heaven and earth, does not dwell in temples made by hands; 25 nor is He served by human hands, as though He needed anything, since He Himself gives to all
people life and breath and all things; 26 and He made from one
man every nation of mankind to live on all the face of the earth, having determined
their appointed times and the boundaries of their habitation, 27 that they would seek God, if perhaps they might feel around for Him and find
Him, though He is not far from each one of us; 28 for in Him we live and move and exist, as even some of your own poets have said, ‘For we also are His descendants.’ 29

“I still have many things to say to you, but you cannot bear them now. " John 16:12
