All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work.
2 Timothy 3:16-17
But the word of the LORD endures forever.” Now this is the word which by the gospel was preached to you.
1 Peter 1:25
The grass withers, the flower fades,
But the word of our God stands forever.”
But He answered and said, “It is written, ‘Man shall not live by bread alone, but by every word that proceeds from the mouth of God.’”
“The secret things belong to the LORD our God, but those things which are revealed belong to us and to our children forever, that we may do all the words of this law.
This Book of the Law shall not depart from your mouth, but you shall meditate in it day and night, that you may observe to do according to all that is written in it. For then you will make your way prosperous, and then you will have good success.
So shall My word be that goes forth from My mouth;
It shall not return to Me void,
But it shall accomplish what I please,
And it shall prosper in the thing for which I sent it.
For the word of God is living and powerful, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart.
