He was certainly political, but I don’t agree that was his primary focus. I’ve probably listened to 250 of his sermons over the years. I haven’t done any analysis of his sermon topics so I may be all wet, but I think of him predominantly as a preacher of the gospel. I see his politics as an extension of his Christian beliefs. I believe he felt it was his Christian duty to defend his land against the tyranny of Rome, just as many other Christians have done through the ages.

That doesn't leave much time for ministry.
