All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:

2 Tim 3:16 (KJV)

   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.

2 Peter 1:21 (KJV)

  The Revelation of Jesus Christ, which God gave unto him, to shew unto his servants things which must shortly come to pass; and he sent and signified it by his angel unto his servant John:

Rev 1:1 (KJV)

   God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets,    

  2Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds;

Heb 1:1-2 (KJV)

 20 Knowing this first, that no prophecy of the scripture is of any private interpretation.

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.

2 Peter 1:20-21 (KJV)

That extraordinary or supernatural divine influence vouchsafed to those who wrote the Holy Scriptures, rendering their writings infallible. "All scripture is given by inspiration of God" (R.V., "Every scripture inspired of God"), 2Ti 3:16. This is true of all the "sacred writings," not in the sense of their being works of genius or of supernatural insight, but as "theopneustic," i.e., "breathed into by God" in such a sense that the writers were supernaturally guided to express exactly what God intended them to express as a revelation of his mind and will. The testimony of the sacred writers themselves abundantly demonstrates this truth; and if they are infallible as teachers of doctrine, then the doctrine of plenary inspiration must be accepted. There are no errors in the Bible as it came from God, none have been proved to exist. Difficulties and phenomena we cannot explain are not errors. All these books of the Old and New Testaments are inspired. We do not say that they contain, but that they are, the Word of God. The gift of inspiration rendered the writers the organs of God, for the infallible communication of his mind and will, in the very manner and words in which it was originally given.

  God cannot Lie!

18 That by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold upon the hope set before us:

Heb 6:18 (KJV)

God is faithful, by whom ye were called unto the fellowship of his Son Jesus Christ our Lord.

1 Cor 1:9 (KJV)
