We don't witness to everyone the same way. The apostles began with Abraham when talking to Jews and Gentiles with an Old Testament background, but with the God of creation, when talking to pagan Gentiles.When Paul came to Athens, he first went to the synagogue, and then to the agora, the marketplace. There he attracted the attention of the intellectual elites, the Stoics and Epicureans. They could not understand what he was talking about when speaking of the resurrection. It did not fit their preconceived notions, their religious framework. So they asked for more. They invited Paul to address them at Mar's Hill, a rock outcropping beneath the Acropolis. There we have a tremendous example of Paul's explanation of the gospel by defining God and then man.
