2Ti 3:16-17 KJV
All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: That the man of God may be perfect, throughly furnished unto all good works.

Joh 17:17 KJV
Sanctify them through thy truth: thy word is truth. 

The Bible, God’s Word is His revelation of TRUTH to this world and that, infact, anything which does not agree with His Word is not truth - making the Bible the ONLY source of truth on this earth.
