Scripture is not the Word of God. Jesus is the Word of God (John 1). "You search the scriptures because you think that in them you have eternal life; it is these that testify about Me; and you are unwilling to come to Me so that you may have life (John 5:39-40)."
When we say things like, 'I only believe what the bible says'. We are really saying that we believe in our interpretation of the bible. One of the greatest idols in our western world is reason. We have given great authority and control to our ability to rationalize and intellectualize truth claims, by so doing we have fallen into deception. When Christ Himself is our foundation, we interpret everything through Him; which means if a challenging idea comes along, it doesn't make us angry or throw us off, but causes us to abide in the source of all revelation.
Having faith in your own revelation makes you unstable, full of fear, frustration, comparison, and bitterness. Faith in the person who is truth, salvation, and wisdom itself allows you to live outside of your own means; and in this way brings peace, rest, joy, and gleeful expectation.
"But by His doing you are in Christ Jesus, who became to us wisdom from God, and righteousness and sanctification, and redemption, so that, just as it is written, 'Let Him who boasts, boast in the Lord.'" (1 Cor. 1:30-31).
