It is not only the church and the school which must be Christian. Every area of life and thought must obey God and His word. It’s a very serious mistake to think of the Bible as a church book. The Bible is more than a church book. It is a book for the totality of life, and as a result, this book is for every man in every area of life, and for every institution. It’s a Bible for church and state, for school and laboratory…
It’s a book for every area of life, and this book is seriously maligned and damaged if it’s treated as a book for the church only. It is to dishonor this book to limit its scope. It’s a book for the courtroom. It’s a book for the state. Every area of life is under God. It must hear His word and must obey Him. This does not mean the union of church and state. It means religion is basic to the state as it is to the church.
