Program of Conquest

Might we consider going the path of the early Christians?  What was their method for winning the Roman Empire? According to Mark Driscoll, we should consider the words of Douglas Wilson:

It will be a great reformation and revival — it will happen the same way the early Christians conquered Rome. Their program of conquest consisted largely of two elements — gospel preaching and being eaten by lions — a strategy that has not yet captured the imagination of the the contemporary church.

~Douglas Wilson, as quoted by Mark Driscoll in his new book, A Call to Resurgence: Will Christianity Have a Funeral or a Future?
