God's Word Is Unbreakable
All scripture is breathed out by God – though He used distinct, individual human authors to record it. This means all of Scripture is a reflection of the mind of God himself. When we say then that God’s word is "unified", we are ultimately reflecting the necessary conclusion that, if Scripture is all God-breathed, then it must be just as unified as God is unified in his own thinking and actions. God is not confused, does not change his mind, does not ever need to grow in understanding because he knows everything and has all wisdom. Therefore, when God speaks in all of Scripture, all of Scripture will agree with itself because God does not ever disagree with himself. This unity of Scripture is expressed nowhere more clearly than in the declaration of Jesus in John 10:35 that "Scripture cannot be broken."
