When Peter stands up and preaches, he is doing far more than just preaching a sermon about some familiar Old Testament passages. In fact, the response of the people tells us all we need to know. They don’t say, “Thanks for the reminder.” No, they say, “What shall we do?” Why would they say such a thing when all they have heard is information?
Because it was not information – it was the proclamation of a whole new reality. It was, for them, a gospel. A message that proclaimed an entirely new reality. And so we ask, “How does the gospel continue to be told and retold?” When we see beyond the gospel only being salvation, we are able to wake up to a brand new world, and ask “What shall we do?”
