This last year the church worked through a fascination book about how the Bible formed our society (The Book that made your World; by Vishal Mangalwadi, 2011). So when this poll came out in January I thought it was interesting how people do not even realise how much they as unbelievers have to be grateful for a book, the Bible, that they do not think is so important.
(Umfrage des Markt- und Sozialforschungsinstituts INSA-Consulere -Erfurt; as found in IdeaSpektrum 52/53 2020; page 6)

The Bible is the most important book in world history:

Yes = 21%
No = 55%
Don't know = 16%
No answer = 8%

A break down of those who said yes:
21% = all Germans

State Churches:
31% = Evangelical Lutherans
31% = Catholic

43% = Free churches
5% = Islam
10% = No confession

Theological Higher Criticism has killed the root of our Western Civilisation over the last 200 years. We have not been taught all the good things we enjoy in the West spring out of the Word of Life.
