Following are just a few of the verses that persuade me of this truth:
For whatever was written in earlier times was written for our instruction, that through perseverance and the encouragement of the scriptures, we might have hope.
But He answered and said, “It is written, ‘Man shall not live on bread alone, but on every word that proceeds out of the mouth of God.’”
II Timothy 3:15-17
. . . and that from childhood you have known the sacred writings which are able to give you the wisdom that leads to salvation through faith which is in Christ Jesus. All scripture is inspired by God and profitable for teaching, for reproof, for correction for training in righteousness; that the man of God may be adequate, equipped for every good work.
II Peter 1:19-21
And so we have the prophetic word made more sure, to which you do well to pay attention as to a lamp shining in a dark place, until the day dawns and the morning star arises in your hearts. But know this first of all, that no prophecy of Scripture is a matter of one’s own interpretation, for no prophecy was ever made by an act of human will, but men moved by the Holy Spirit spoke from God.
And beginning with Moses and with all the prophets, He explained to them the things concerning Himself in all the Scriptures. . . Now He said to them, “These are My words which I spoke to you while I was still with you, that all things which are written about Me in the Law of Moses and the Prophets and the Psalms must be fulfilled.”
. . . having been built upon the foundation of the apostles and prophets, Christ Jesus Himself being the corner stone.
But even though we, or an angel from heaven, should preach to you a gospel contrary to that which we have preached to your, let him be accursed.
Thy word is a lamp to my feet,
And a light to my path.
The unfolding of Thy word gives light;
It gives understanding to the simple.
For truly I say to you, until heaven and earth pass away, not the smallest letter or stroke shall pass away from the Law, until all is accomplished.
To the law and to the testimony! If they do not speak according to this word, it is because they have no dawn.
You search the Scriptures, because you think that in them you have eternal life; and it is these that bear witness of Me.
Let the word of Christ dwell richly within you, with all wisdom teaching and admonishing one another with psalms and hymns and spiritual songs, singing with thankfulness in your hearts to God.
