Source of Authority
When confronted by Satan, Jesus appealed to the Old Testament as a source of authority by stating, "It is written," (Matt. 4:4, 7, 10).
Imperishability
"For truly I say to you, until heaven and earth pass away, not the smallest letter or stroke shall pass from the Law until all is accomplished," (NASB, Matt. 5:18).
Unbreakability
"The Scripture cannot be broken," (NASB, Jn. 10:35).
Source of Doctrinal Authority
Jesus appealed to Scripture when correcting false doctrine stating, "You are mistaken, not understanding the Scriptures nor the power of God," (NASB, Matt. 22:29).
Truthfulness
"Your word is truth," (NASB, Jn. 17:17).
Historical Reliability
Jesus affirmed the historical existence of Jonah (Matt. 12:40), Noah (Matt. 24:37-38), and Adam and Eve (Matt. 19:4-6).
Scientific Reliability
Jesus affirmed that God created the world (Mk. 13:19; cf. Matt. 19:4).
Old Testament Canonicity1
Jesus made reference to the Law and Prophets as a unit, "Do not think that I came to abolish the Law or the Prophets; I did not come to abolish but to fulfill," (Matt. 5:17).
Jesus explained the Scriptures, "Then beginning with Moses and with all the prophets, He explained to them the things concerning Himself in all the Scriptures," (NASB, Luke 24:27).
Jesus referred to the entire Canon by mentioning all the prophets from Abel (from Genesis, the first book and first martyr) to Zechariah (Chronicles, the last book, and the last martyr) (Matt. 23:35).2
