I just watched this film last night. It is an awesome film about someone who God used to change the course of history (His-story).
One phrase that struck me the most was one said by John Newton, He is old and blind by this point and he says
"There is only two things I now remember, I am a great sinner and Christ is a great Saviour."
I was struck by this and know for myself the truth of this. There is only one name by which we are saved.
I definitely recommend seeing the film, when asked what I thought initially I said it was a bit long and takes awhile to get going but then thinking about it how much longer did it feel fr William Wilberforce!!!
