Gann Quotes in a book :

W.D.Gann referenced : 

"The Bible is the BOOK of all books, and if we only study it and understand it, we can gain a proper knowledge of all things. I believe it the duty of any man who understands science and mathematics and the cycle theory, and knows what is coming, to warn the people in order that they may prepare for trouble ahead. 

Many will scoff and laugh and refuse to believe until it is too late. The Bible is full of references where God has given us signs by which we may know what is coming, if we will only believe them.
