You mean it isn’t social media?
This is one area where I think our modern, Western context does not square neatly with what we see in Paul’s 1st century context. The people Paul preached to were at least overtly theistic in their world views in one way or another.
Paul’s first audience, of course, were Jews, and the early ministry of the gospel to them was a very unique one. Paul was coming at them as a former Pharisee and persecutor of the church. The Jews had just murdered Jesus; the destruction of Jerusalem was prophesied as imminent, etc. While there is neither Jew nor Greek in Christ, the Jews will nevertheless always be a unique audience as it relates to the gospel.
And his second audience – these 1st century Greek and Roman Gentiles – were at least explicitly religious in their of viewing the world. I’m not an expert on the era, but it’s my understand that even the philosophers, for all their worldly wisdom, only toyed with the idea of atheism or agnosticism, but for the most part gave patronage to the Greek pantheon if for no other reason than to at least remain in public favor. Exceptions to this like Protagoras existed, who was an open agnostic, but the people hated him for it and ended up burning his books. By contrast, Epicurus thought little of the gods, but at least acknowledged them.
Paul was at least speaking into a theistic context. People understood and acknowledged the concepts of divine power, of sovereign rule (Caesar’s, at least), and operated out of a general acknowledgement of moral objectivism and some conception of sin or accountability to cosmic authority. By contrast, our modern context is none of these things. We’ve labored very hard for the last few generations to suppress the knowledge of sin, the knowledge of God, and to eradicate every sense of authority besides our own will. If our emotions validate us, that’s all that matters. We’ve come a long way from a 1st century context. That isn’t to say that our gospel changes, obviously, but the way we bring it to bear on the culture certainly has to, simply because there is so many more fundamental facts about reality that need to be established with people before the gospel even makes sense to them.
I often think about Acts 14:1, where Paul was at Iconium and “spoke in such a way that a great number of both Jews and Greeks believed.” I want to know what that looks like for us today.
