2 Timothy 3:
What is the mechanical process of being God-breathed?
One way was described in Numbers 12:
Concerning the design plans of the temple, 1Ch 28:
I don't think so. God inspired him generally to write this book of Ecclesiastes. Regarding this particular verse, the stress is on the I, the author himself. He inserted his personal opinion or bias here.
In the NT, Peter wrote in 2 Peter 1:
The Holy Spirit inspires a prophet's human spirit. The Holy Spirit breathes into the human spirit to communicate a word/thought from God. The prophets wrote them down as sacred scriptures. It is a spirit-to-spirit communication.
At Biblehub, 13 versions use inspired by or of God; 10 versions use God-breathed16 All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness,
What is the mechanical process of being God-breathed?
One way was described in Numbers 12:
There were other methods, Job 32:8 I speak with him [Moses] face to face, clearly and not in riddles; he sees the form of the LORD. Why then were you unafraid to speak against My servant Moses?
I'd define God-breathed as the process of a sacred word/thought breathed out by God to inspire a human's spirit to record it in a human language.8 But it is the spirit in a person, the breath of the Almighty, that gives them understanding.
Concerning the design plans of the temple, 1Ch 28:
The communication was quite specific and detailed.11 Then David gave his son Solomon the plans for the portico of the temple, its buildings, its storerooms, its upper parts, its inner rooms and the place of atonement. 12He gave him the plans of all that the Spirit had put in his mind for the courts of the temple of the Lord and all the surrounding rooms, for the treasuries of the temple of God and for the treasuries for the dedicated things.
Jeremiah experienced this process in 36:19“All this,” David said, “I have in writing as a result of the Lord’s hand on me, and he enabled me to understand all the details of the plan.”
The LORD spoke the words to Jeremiah. Jeremiah dictated them to Baruch. Baruch wrote them down. But the king didn't like it and destroyed this scroll.4 Jeremiah called Baruch the son of Neriah, and Baruch wrote on a scroll at the dictation of Jeremiah all the words of the LORD that he had spoken to him.
Once again, Jeremiah was inspired and obeyed.27 Now after the king had burned the scroll with the words that Baruch wrote at Jeremiah’s dictation, the word of the LORD came to Jeremiah: 28 “Take another scroll and write on it all the former words that were in the first scroll, which Jehoiakim the king of Judah has burned.
Note that this 2nd scroll was not identical to the first one, even though both were inspired. In both cases, 1 Thess 2:32 Then Jeremiah took another scroll and gave it to Baruch the scribe, the son of Neriah, who wrote on it at the dictation of Jeremiah all the words of the scroll that Jehoiakim king of Judah had burned in the fire. And many similar words were added to them.
More generally, Ecclesiastes 7:13 When you received the word of God, which you heard from us, you accepted it not as the word of men but as what it really is, the word of God
In the above, did the writer of Ecclesiastes quote from the mouth of God?28 while I was still searching but not finding— I found one upright man among a thousand, but not one upright woman among them all.
I don't think so. God inspired him generally to write this book of Ecclesiastes. Regarding this particular verse, the stress is on the I, the author himself. He inserted his personal opinion or bias here.
In the NT, Peter wrote in 2 Peter 1:
There is a bit of circular or recursive reasoning in this OP: I believe that the Scripture is God-breathed because the Scripture says it is. This is an axiomatic tautology.16 For we did not follow cleverly devised stories when we told you about the coming of our Lord Jesus Christ in power, but we were eyewitnesses of his majesty. …
20 knowing this first of all, that no prophecy of Scripture comes from someone’s own interpretation. 21 For no prophecy was ever produced by the will of man, but men spoke from God as they were carried along by the Holy Spirit.
The Holy Spirit inspires a prophet's human spirit. The Holy Spirit breathes into the human spirit to communicate a word/thought from God. The prophets wrote them down as sacred scriptures. It is a spirit-to-spirit communication.
