A loving God is one that makes himself known, and doesn't hide himself or hide behind a cloak of incomprehensibility. If he loves you, he's got to reveal himself, because he's apparently invisible.
God has graciously done that. He's revealed himself in his word, the Bible, which is also called the scriptures. It is God's Word.
You've first got to come to this place, where you believe that if there is a God, then he must be a loving God, or he's not worthy to be called God. You come to the scriptures to find out if the God of the Bible is that loving God.
2 Peter 1
20 Knowing this first, that no prophecy of the scripture is of any private interpretation.
21 For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost.
If God had gone to the trouble of revealing himself, then these verses of scripture make a lot of sense. They should be paramount in the mind of anyone who wants to enjoy and understand the Bible.
The Bible, God's Word, did not come by the will of man. An individual or a committee did not sit down and say "Now I am going to write a book, and that book will be called the book of Genesis". Holy men of God spake as they were moved, as they were instructed to speak by the Holy Ghost, or Holy Spirit. And holy men of God wrote as they were instructed to write. They wrote exactly what God told them to write. Word for word, verbatim. God would have spoken to holy men of God with words and language with which the men were familiar, and in a manner in which the men could understand.
The word "holy" means separated from the common lot. A holy man of God is a man who God has made holy. He, God, has separated them from the common lot of people. According to John 4:24, God is spirit, and according to 1 Peter 1:16 God is holy. God is Holy Spirit, and is the originator of the words of the Bible. Holy men of God spake as they were moved by the Holy Spirit, that is, as they were moved by God.
The word "private" in verse 20 is in the Greek idios, which means "one's own" or "his own". No prophecy of the scripture is of one's own interpretation. The word of God and the words of God, the scriptures, mean exactly what God means them to mean, and the point is not open for discussion as far as God is concerned.
You'll notice the verse doesn't say that men and women alike aren't going to go around and offer their own private interpretation to whoever is willing to listen. And if you've been around at all yourself, you know that there are many who do just that. It becomes exceptionally difficult to enjoy the Bible when you do that yourself or subject yourself to someone else's private interpretation.
If you want to appreciate and enjoy the Bible, then it is paramount that you bring no private interpretation to it when you read and study it. That can be a difficult chore when we've been brought up to to do so all of our lives. You can just let it all go, and let God's word speak for itself.
To enjoy the Bible, you've got to first simply read what is written on the page. You don't add to it, or embellish it, or delete from it, or alter it to fit your beautiful preconceived ideas. Almost all of God's word explains itself right where it is written, and in the context where it is written. Sometimes you have to read a remoter context to see the meaning, and sometimes you have to read an entire book of the bible to understand the context in which a particular verse of scripture sits. But easily 90-95% of God's word can be understood just right there, where it is written. You don't need a commentary.
2 Timothy 3:16
All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness
All scripture given by inspiration of God. All of it. "Inspiration" is Gr. theopnuestos, God breathed. It came from the mouth of God. Since that is the case, then when we come to the scriptures, and read and study them, we should offer them the utmost possible respect that you could give to any words.
2 Timothy 2:15
Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.
"Rightly dividing" is Gr. orthotomeō. You might recognize the prefix, ortho, in such words as orthogonal, or orthopedics. If two lines are orthogonal, they are at right angles to each other, or the angle between them is 90 degrees. If the two lines met at an angle of 89.999999999 degrees, you couldn't say they were orthogonal. The rest of the word means to cut, or cutting. We are supposed to "rightly divide", rightly cut, or make straight cuts when working God's word. If you do that, you'll have no need to be ashamed of your workmanship. And you'll be able to enjoy the Bible as God intended you to enjoy it.
