Psalm 12:6 (KJV)
6 The words of the LORD are pure words: as silver tried in a furnace of earth, purified seven times.
REV 22:18-19[KJV]
18 For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book:
19 And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and [from] the things which are written in this book.
1 Peter 1:25 - But the word of the Lord endureth for ever. And this is the word which by the gospel is preached unto you.
2 Timothy 3:16 - All scripture [is] given by inspiration of God, and [is] profitable for doctrine, for reproof, for correction, for instruction in righteousness:
Romans 15:4 - For whatsoever things were written aforetime were written for our learning, that we through patience and comfort of the scriptures might have hope.
Isaiah 40:8 - The grass withereth, the flower fadeth: but the word of our God shall stand for ever.
Hebrews 4:12 - For the word of God [is] quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and [is] a discerner of the thoughts and intents of the heart.
2 Peter 1:21 - For the prophecy came not in old time by the will of man: but holy men of God spake [as they were] moved by the Holy Ghost.
Psalms 119:105 - NUN. Thy word [is] a lamp unto my feet, and a light unto my path.
1 Thessalonians 2:13 - For this cause also thank we God without ceasing, because, when ye received the word of God which ye heard of us, ye received [it] not [as] the word of men, but as it is in truth, the word of God, which effectually worketh also in you that believe.
Sounds like big statements to me.
