To me, this means that God can use any scripture, at all, for all four things > teaching knowledge with perspective, rebuking and standing against what is not of God's love, correcting a person to become loving like Jesus, and helping the person to live the way God's love has us being and living right.
Each word is what God has given the person to write . . . however He has done this.
God is our Creator, and I find He is very creative; so "how" He deals with each author can be . . . different
I think, among other possibilities, that He can >
a. Have a person thinking what He wants the person to write.
b. The Holy Spirit can bring to remembrance what he has already heard and have him write what the Holy Spirit has him remember > consider John 14:26.
c. Talk directly with the person and dictate what the person is to write > dictating with an audible voice or using the tone of voice used by the person in one's own thinking, except the person realizes he is not doing his "thinking", on his own
d. Like how John received the book of Revelation > he was "in the Spirit on the Lord's Day" (Revelation 1:10), and Jesus appeared to him, and all that was involved in writing the book of Revelation. In one place it seems he was writing, right while experiencing the vision of revelation, but he was told not to write some things he heard > Revelation 10:4. So, in this case, there were various dynamics going on, from the beginning of the inspiration to the end. I would say there was observation with written description, dictation at times, and recording things after they happened. And Jesus gave John those letters to the seven churches, included in the process. So, there can be inspired messages within the inspired message
e. If I remember the early scripture prophets right, ones had visions and wrote descriptions of what they saw, and could have discussion, even two-way, with God about their meaning.
The main thing I see is that the person is able to communicate and share personally with God. And God has him or her share something from a special time with God. So, love inspires
Whatever God inspires is inerrant. But how we understand and live His message needs to be what He means! This is an adventure
This is "why" . . . I think . . . Paul starts certain letters with something like "Grace to you and peace from God our Father and the Lord Jesus Christ" > because grace is God's action personal of His love in us changing us to become how His word means for us to be, and this grace also has His own personal guiding to do what He means. So, God's word is meant to have His grace and peace escorting us. God's grace and peace in us demonstrates all that God means, by actually having us do all He knows His word means. So . . . then . . . His grace with His leading is without error!!!
What He actually does with us in His love is the only reliable way, really, to interpret scripture.
They mean any writing that Jesus or Paul or Peter or any other New Testament writer quotes from. And they mean all the New Testament . . . even if certain ones had not been written, yet, when Paul wrote that > God meant also any future writings that He would grant us, later.
And, by the way, Paul clearly does say "you are an epistle of Christ", in 2 Corinthians 3:2-3. So, the Holy Spirit has written in our hearts; whatsoever the Holy Spirit writes in us is Canon Scripture, I would say
"And this writing can be deeper than the words > the love of God is the ink effecting us to become exactly how Jesus is and so we are loving the way Jesus has loved us. No words alone can have us doing all Jesus means when He says "'This is My commandment, that you love one another as I have loved you.'" (John 15:12)
No words alone can have us loving the way Jesus has loved us > we need the ink, not only what we can think
And Jesus in us is the Word who is the living meaning and fulfillment of all His message
Why do I think so? It is past my ability to know why
My understanding of evangelical, in simple terms, is they say the Bible is God's word, without any error, including in science. So, if anything contradicts God's word, that "anything" is wrong and God's word is right.
I would offer a clarification > God's word is not in error in what God means, but how we understand it can be in error. So . . . again . . . we need grace in us to have us being and doing all that God means . . . how His love has us becoming and what His leading personal in each of us has us doing.
And we have demonstration, of the Holy Spirit > 1 Thessalonians 1:5-10 > so we have all which His words mean
And His word, Paul says here in 1 Thessalonians 1:5-10, came with example. And Jesus said to love and demonstrated how to love. So, we need the demonstration of examples > 1 Timothy 3:1-10, 1 Peter 5:3, 1 Thessalonians 2:5-12, 1 Corinthians 11:1, Ephesians 5:1-2. In Ephesians 5:1, it says to imitate God. I experience that this means how our Father in us shows us how He is and how He loves, and then He has us becoming and loving this way, more and more as we grow in Jesus. So, we have God's own example in us
so we have the really right meaning of His word.
