The Bible is God's inspired Revelation to man. It is the process by which select persons were enabled through writing to carry special information about the one true God to their fellowman.
The men used to write the Bible were firstly, men that believed God and secondly were obedient to God. They wrote in the Spirit and the love of God. They were empowered to speak.
God inspired the thought and the principle while the chosen men wrote it in their style.
