On the surface, "Jesus shows us what God is really like" language appears pious and even Jesus-exalting. In reality, it betrays a tragically truncated view of the Jesus of the Bible. We see God "as he is" by gazing with the eyes of faith on the pages of his Word—all of them.
It is instructive, then, to see that Paul takes the gospel literally into the public square. It means that he did not see the Christian faith as only able to change individual hearts. He believed that the gospel had what it took to engage the thinking public, the cultural elites, and to challenge the dominant cultural ideas of the day. He was after converts of course—he was first and foremost a church planter, not a theologian or Christian philosopher. But he wouldn't have been able to engage the hearts of cultural leaders unless he also engaged the ideas of the culture itself. He did not shrink from that challenge. He did not merely try to find individual philosophers to evangelize in a corner. He addressed them as a culture, a public community.
