What the Bible says about Scripture, Infallibility of
(From Forerunner Commentary)
Jesus is engaged in a discussion in which He is accused of blaspheming God. He uses this scripture, quoting from Psalm 82:6, to support His assertion that He is the Son of God. That verse cannot be declared to be irrelevant; it carries the weight and authority of God because He inspired it. God's Word is truth; what He says is true. We cannot simply discard it because we disagree with it. If we do, we are, in effect calling God a liar.

Revelation 2-3 and Works
How clear! It was so clear that those who were challenging Him could not answer Him. "The Scripture cannot be broken" means God's Word is indestructible, no matter how fallible men may regard it. In this case, Jesus means that the Old Testament is inspired, infallible, and authoritative. The New Testament is every bit as authoritative and reliable as the Old, as the same God inspired it for the same overall purpose!
