I’ll take some flack for this, but it is MY belief, based on his writings and speeches just in the last few years that this latest wife AND HER PARENTS led Newt into an ACTUAL and GENUINE personal relationship with THE LORD JESUS CHRIST.
The “starter” for this line of thinking was the book, and I think there might also have been a corresponding video, showing the multitudes of appeals to God, mentions of God, quotations of Scripture, etc., in the Founding Documents of our Nation, the Shrines and Monuments, and the Government Buildings, etc. in DC.
I also was thinking that it seems that maybe his wife has made a real difference in the man.
