As it has been previously posted, the Word of God is not only what has been written on paper. For example, 2 Thessalonians 2:15.
“So then brethren, stand firm and hold to the traditions which you were taught, whether by *** word of mouth ***or by letter from us.”
If you wish to know how we will be judged upon the last day, read Matthew 25:31-46.
You will see who goes into heaven and who does not, and why.
Furthermore, in relation to the “Word of God” statement in John, in the beginning of that Gospel, it is said that the Word was with God, and the Word was God. That Christ was that Word, the Living Word of God. Therefore, that verse probably still does not hold water when tested in that way. But the previous scriptural quote that I’ve just added also helps.
