It's also the Christian book, and what all Christians believe.

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

2 Timothy 3:
10But thou hast fully known my doctrine, manner of life, purpose, faith, longsuffering, charity, patience, 11Persecutions, afflictions, which came unto me at Antioch, at Iconium, at Lystra; what persecutions I endured: but out of them all the Lord delivered me. 12Yea, and all that will live godly in Christ Jesus shall suffer persecution. 13But evil men and seducers shall wax worse and worse, deceiving, and being deceived. 14But continue thou in the things which thou hast learned and hast been assured of, knowing of whom thou hast learned them; 15And that from a child thou hast known the holy scriptures, which are able to make thee wise unto salvation through faith which is in Christ Jesus. 16All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: 17That the man of God may be perfect, throughly furnished unto all good works.
