To answer this question I think we should examine HOW inspiration occurs. Russell described how he was "inspired" by God:
Zions Watchtower June 1916
HARVEST GATHERINGS AND SIFTINGS
MANY are the inquiries relative to the truths presented in the STUDIES IN THE SCRIPTURES and THE WATCH TOWER, as to whence they came and how they developed to their present symmetrical and beautiful proportions. Were they the results of visions? Did God in some supernatural way grant the solution of these hitherto hidden mysteries of His Plan? Is the author of these writings more than an ordinary being? Does he claim supernatural wisdom or power? Or how comes this revelation of God's Truth?
No, the truths we present, were not revealed in visions and dreams or by God's audible voice; nor were they revealed all at once, but gradually...

I told him that I realized that He was the Shepherd and not I, but I knew also that he would be pleased with my interest in the sheep and my desire to be His servant and to declare the Truth, the Way and the Life to them; that I felt deeply impressed that if the time had come for the permission of a false view to deceive the unworthy, it must also be His due time to have the truth on the same subject made clear, that the worthy ones might be able to stand, and not fall from the Truth.
Believing that the due time had come for the correct understanding of the meaning of the Jewish sacrifices which all Christians see were typical of "better sacrifices," and trusting that the Lord would grant the insight as soon as I got into the attitude of mind best fitted to receive the light, I prayed with confidence...

***********
So here's how God inspires: by guiding thoughts, actions, and attentions; by answering prayers and implanting ideas.
Suppose someone believed their thoughts were being guided by God, but they were mistaken?
Genesis contains the account of Noah and the flood. I've read many discussions about the flood itself. Because this was a single event which happened thousands of years ago the debate may never be conclusively ended. I look at an event in the same account that repeats itself every day. Namely: "Ge 9:13-14 "I set My bow in the cloud, and it shall be for a sign of a covenant between Me and the earth. And it shall come about, when I bring a cloud over the earth, that the bow shall be seen in the cloud,..." Ge 9:16 "When the bow is in the cloud, then I will look upon it, to remember the everlasting covenant between God and every living creature of all flesh that is on the earth." Some bibles say "rainbow", so I studied the hebrew word. The same word is used 4 other times in Genesis (21:6, 27:3,48:22, & 49:24), all refer to a bow and arrow. Throughout the bible this same hebrew word is descibing a bow (a weapon). Common sense tells me that hanging up your weapon (your bow) would be viewed as a sign of peace as stated in the account. It "fits" the meaning of the account. Therefore I believe "bow" is more correct.
My hypothesis: An ancient hebrew who works outdoors (let's say a shepherd) gets caught in a thunderstorm. As scary as this would be for you or I, this man "knows" that God and his angels control the wind, rain, lightning, and thunder. He would logically conclude that God was angry with him. Perhaps he prays and asks God to spare him. Then something wonderful happens. The storm stops, the sun comes out and a beautiful band of color appears in the sky. Since God heard the shepherd's prayer, perhaps the shepherd can receive communications from God as well. Maybe not the actual "voice" of God, but a guided thought process. He prays for divine guidance in solving the mystery of this beautiful thing in the sky. Using his knowledge and reason he examines the evidence: 1) this thing is in heaven therefore it belongs to God 2) It is arched like a bow , so it might be God's bow 3) It appeared after the violence of the storm ended, so it may be a sign of peace. Conclusion: God hangs His bow on a cloud as a sign of peace after the violence of the storm.
To check my hypothesis I realized that if God had a bow He would also have arrows. I did a word search for arrows in the bible: "Psa77:17 The clouds poured out water: the skies sent out a sound: thine arrows also went abroad. 2 Samuel 22:15 He shot arrows and scattered [the enemies], bolts of lightning and routed them. Psalm 18:14 He shot his arrows and scattered [the enemies], great bolts of lightning and routed them. Psalm 144:6 Send forth lightning and scatter [the enemies]; shoot your arrows and rout them. Psalm 64:7 But God shall shoot at them with an arrow; suddenly shall they be wounded. Num24:8 God brought him forth out of Egypt; he hath as it were the strength of an unicorn: he shall eat up the nations his enemies, and shall break their bones, and pierce them through with his arrows. Deu32:23 I will heap mischiefs upon them; I will spend mine arrows upon them. Psa7:13 He hath also prepared for him the instruments of death; he ordaineth his arrows against the persecutors." Conclusion: the bible says a rainbow is God's bow and lightning are His arrows.
While the shepherd sincerely believed he was given divine guidance in determining the true nature of a rainbow, I question if this part of the bible was really from God or merely from the mind of man. Common knowledge tells me that rainbows are refracted light and lightning is a discharge of electricity. In describing the above to a christian friend, he presented the following arguments:
1) God "dumbed-down" the truth so it would be acceptable to the understanding of the men at that point in history. My reply: Noah had just been saved from the greatest diaster of all time BECAUSE of his faith in what God said, do you really think he would quit trusting what God said NOW? For example, if God said, "Dear Noah all the colors you see there are contained in the light of the sun."; would Noah really question this? Also, I believe God's message is written for all men at all times, not tailored to one point in history.
2) This part of the flood account could be figurative, not literal. My reply: Many christians feel free to split a single story into some literal parts and some figurative parts, but still claim it as "true". In this case my friend believes the flood occurred literally, but the rainbow part is figurative. I could just as easily claim the whole story is figurative. Some religions even split a single verse. There seems to be no logic or reason to this labeling. Who decides what is literal and what figurative? Can it all be figurative? I think you must read and study and decide for yourself.
3) The bible is a spiritual book, not a scientific one. My reply: I agree! That is why I don't find it necessary to claim that every single word is from God Himself to understand the spiritual message contained in the bible. You are of course free to believe that God uses a rainbow to shoot lightning arrows to earth, thus making every word "true".
