Actually, it is not human logic, it is Scripture.
But to the point. We certainly do have a role to play in the advancement of the Gospel. God gave us free will, after all. So no, my logic and common sense does not tell me to stand idle while evil marches on, either as an individual or as a citizen of my country.
In addition, I know several devout Baptists of varying educational levels and they all are solidly in the Romney camp, knowing full well he is a Mormon. They have access to information and a mind of their own. Dr. Graham’s website has no bearing on which lever they will pull.
I wish I could have heard their talk, but I can guarantee Mr Graham NEVER gave up Jesus as his Saviour.
