Paul's Method

Prompted by Roy Joslin's Urban Harvest I have been considering Acts 14:8-20. Joslin uses it to illustrate preaching to the 'working man'.

But here's a conundrum I can't resolve yet. Following the healing of a man, the people want to worship Paul and Barnabas. In horror, they address the crowd. And here's the problem: Christ is not preached. Perhaps the preaching of Christ is implicit in v15: "...we are bringing you good news...". But the fact that it is not explicit suggests to me that Paul's evangelistic method is not the main emphasis here, but something else.

Am I off track here?

I think I need to raid more of my bookshelves...
