All of Scripture, in its totality and its parts, is a means to an end and an instrument for a purpose. It is not a goal in itself, but as its grand objective the equipment of man for the service of God. It is freely produced by human writers, but its original Author is God Himself. Through the service of human writers, God breathed out the Scriptures so that they are not only human words, but simultaneously and ultimately the very utterances of God. Inspiration does not just pertain to the persons who penned Scripture.
Inspiration encompasses every word and all the words of the sacred writings.
Therefore the scriptures are fully consistent and inerrant, authoritative and trustworthy, in everything that they assert, in every area that they address and in every way that they speak. As such they are perfectly suited to reach their intended objective. So now, brethren, I commend you to God and to the word of His grace, which is able to build you up and give you an inheritance among all those who are sanctified.
