From the WTS website:
Other books and articles have now been published claiming that this hidden code provides absolute proof of God's inspiration of the Bible. Does such a code exist? Should a hidden code be the basis for believing that the Bible is inspired of God?
Then the article goes on to list some different methods of how some try to find these hidden codes. Then the article ends up:
The apostle Paul very clearly wrote that "all Scripture is inspired of God and beneficial for teaching, for reproving, for setting things straight, for disciplining in righteousness, that the man of God may be fully competent, completely equipped for every good work." (2 Timothy 3:16, 17) The clear and straightforward message in the Bible is not too difficult to understand or apply, but many people choose to ignore it. (Deuteronomy 30:11-14) The prophecies that are openly presented in the Bible give a solid basis for believing its inspiration.% Unlike a hidden code, Bible prophecies are not arbitrary, and they do not 'spring from any private interpretation.'— 2 Peter 1:19-21.The apostle Peter wrote that "it was not by following artfully contrived false stories that we acquainted you with the power and presence of our Lord Jesus Christ." ( 2 Peter 1:16) The concept of a Bible code has its roots in Jewish mysticism, utilizing "artfully contrived" methods that obscure and distort the plain meaning of the Bible's inspired text. The Hebrew Scriptures themselves unequivocally condemned such a mystical approach.—Deuteronomy 13:1-5; 18:9-13.
How happy we are to have the Bible's clear message and instruction, which can help us to know God! This is far better than trying to learn about our Creator by searching for hidden messages that are the products of private interpretation and computer-assisted imagination.—Matthew 7:24, 25.
So, after reading this how would a JW explain how they come up with the 1914 date of Jesus' invisible return? Is that part of the Bible's clear message and instruction? Or is it some artfully contrived false story?
