What kind of Christian admits publicly that he has never asked God for forgiveness? And that he doesn’t really know of anything for which he needs forgiveness?

I think the specifics of Trump’s Christianity are none of your business. Take a look at Abraham Lincoln’s religious views and habits. Was he a moral man and a good Christian as president? I say yes.
