John 17:17
17 Sanctify them by the truth; your word is truth.

Romans 15:4
4 For everything that was written in the past was written to teach us, so that through endurance and the encouragement of the Scriptures we might have hope.

2 Timothy 3:16
16 All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness,
17 so that the man of God may be thoroughly equipped for every good work.

2 Peter 1:19-21
19 And we have the word of the prophets made more certain, and you will do well to pay attention to it, as to a light shining in a dark place, until the day dawns and the morning star rises in your hearts.
20 Above all, you must understand that no prophecy of Scripture came about by the prophet's own interpretation.
21 For prophecy never had its origin in the will of man, but men spoke from God as they were carried along by the Holy Spirit.
