Observation: I recently saw an archeological review of Caesarea, which was an interesting city. It was a city constructed by the Romans, with a manmade port and breakwater. The port was at the northern end of a large, rocky bay, and had a large temple to Caesar right at the mouth of the port. The city extended south along the bay, with a hippodrome occupying much of the land there, and ended with the governor's palace perched on the southern promontory of the bay. And set just inland from that palace (logistically attached even to the palace) was one more significant house that would have been the home of the most prominent military commander over the city. It is believed that was, in fact, where Peter met Cornelius, and where the Holy Spirit then first came down upon Gentiles.
This was Rome's capital in Judea. This is the footprint of Rome itself in the borders of Judea/Israel, and this very location represents everything about that worldly power dynamic ... a large temple for Caesar worship, a palace for the local leader, a massive entertainment venue to impose Roman 'culture' into the lives of the people, and a military post to enforce it all. And smack in the middle of all that, the Holy Spirit shows up for the first time to reenforce that salvation is for all, Jews and Gentiles alike, and that story would become the fire of encouragement the rest of the Church needed to go to the ends of the world with the gospel.
Clearly, if the Holy Spirit can show up in the heart of the Roman capital, to be poured out on high-ranking Roman military officials and Roman citizens, it can show up anywhere and bless anyone.
Application: It is not too dramatic to state that this benchmark event in Caesarea is the ignition point that led to my salvation. It is one of the key reasons the gospel went to the rest of the world, which eventually included places where I could hear about it millennia later.
In seeing the archeology of the city, I would expect that Peter required great courage to go there, not so much because he feared persecution at that point, but because even just walking into this area of the capital was likely a tenuous act by a Jew. He effectively walked through the military base, beyond the residential areas, up to the very doorstep of the Roman governor's palace, and preached to a roomful of (likely armed) members of the Roman military and their families.
While not quite the same, this represents how I should act whenever I am in a place that is hostile toward Jesus. I have been in those places at work, serving at parades, walking downtown, and even in online forums. These can be "dangerous" places for Christians in this region, and in my case they often represent a kind of earthly political power that could (and has) make my life difficult. I hope I will always have the courage to speak the truth about Jesus, and that my action may therefore create a chain of events that someday saves someone I've never met.
Prayer: Lord, your ways are amazing. As I consider how your plans have always been great, and your ways above any thoughts of the ways of men, may I also find the courage to always speak 'Christ crucified' to all. Amen.
