It is a serious question. Here we have a book purported to be to be inspired by God who is said to be one and gave us the book so we could be one with Him and each other and yet we are as scattered and frayed rather than united as one against the enemy of our souls.
Now if we were one with God and each other it would extend well beyond shallow virtue signaling displays where we pretend that everyone's point of view is equal but are are actually rolling our eyes behind our flickering screens. God's singularity is one in thought and purpose, drawn to the pure light of absolute truth. That truth being revealed to us by the bible.
But instead we read texts that cut across our beliefs and, surprise, our beliefs trump scripture, but even that truth we obfuscate by rationalizing or dragging the text off into the tall weeds of Greek where we beat it to death with our toy sand shovels. Pretending to be Greek scholars is a favorite pass time here on the range. No, we can only take texts we approve of at face value, all others need to be processed at our internal re-education camp and made into some things else. The old "it is what it is and it is not something else" rue went out the window along time ago, after all what do biblical translators know anyway--they didn't ask me first!
I think that if we are all reading from the same book, we should be fairly close to being unified but, alas, the book had not changed us--we have changed it. Made it suite our needs. Of course even this is not the truth. The truth is, the book has not failed, we have.
Let us be broken n the Rock!
It seems the "Book" itself explains the reason for this phenomenon in the Examples which were written for our admonition, as Paul explains;
Rom. 1:
19 Because that which may be known of God is manifest in them; for God hath shewed it unto them.
20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:
21 Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened. 22 Professing themselves to be wise, they became fools,
There are a great many examples of this very thing through out the "Book", but the very first example set's the stage in my view.
Gen. 3:
1 Now the serpent was more subtil than any beast of the field which the LORD God had made. And he said unto the woman, Yea, hath God said, Ye shall not eat of every tree of the garden?
2 And the woman said unto the serpent, We may eat of the fruit of the trees of the garden:
3 But of the fruit of the tree which is in the midst of the garden, God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die.
Here we have Eve who was shown "
that which may be known of God". She
saw the many Freedoms she had in God, and also
saw the limits God placed on her and also knew the dangers of refusing to glorify God in this way. She had no excuse.
4 And the serpent said unto the woman, Ye shall not surely die:
But to test her faith, God placed "another voice" in the garden who told her God was Lying to her. This "other voice" went on to offer her another religious philosophy, contrary to what her God had given her.
5.
For God doth know that in the day ye eat thereof, (Transgress the Commandment) then your eyes shall be opened, and ye shall be as gods, knowing good and evil.
So EVE, when given the choice between God, and the "other voice" which offered a much smoother religious philosophy, chose the "other voice" over God's.
So when Eve knew God, she didn't glorify Him as God by placing her trust in Him and His Word, and her foolish heart was darkened as Paul also tells us..
6 And when the woman saw that the tree was good for food, and that it was pleasant to the eyes, and a tree to be desired to make one wise, (All Contrary to what her God had told her) she took of the fruit thereof, and did eat,
"Professing herself to be wise, she became a fool,
"
and gave also unto her husband with her; and he did eat."
And she shared this Philosophy with others which is how the serpent increases its power to deceive.
This same scenario is repeated over and over through out the entire "Book".
We also have examples of faithful men, who did Glorify God when they knew Him. Like Abraham who left the "other voice" and followed God as God instructed him. We have Shadrak, Meshack and "To bed we go", (As I used to read to my young daughter before bed) who refused the "other voice" even at risk of their own life.
Sadly though, men really don't believe in this God, nor His Freedoms that HE allows His people, nor the restrictions HE places on them for their own good, like Eve. Nor do they believe in the danger God tells them of, for rejecting His instruction.
They choose to believe instead, in the "other voice", which convinces them there is no death, and that God's instructions make them blind, burdens them, and they condemn believers as "Legalists" and such.
There is no Division between God/Christ and Abel, Noah, Abraham, Moses, Caleb, Joshua, Gideon, Alisha, Malachi,Peter, James, Paul, John, Cornelius etc., etc, AKA "The Body of Christ". These all chose to Glorify God when they knew Him, and rejected the "Other voice" in the garden.
It's really quite simple, and Prophesied. We just need to Glorify God, like His Son and the examples of faithful men did.
2 Cor. 11:
3 But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ.
4 For if he that cometh (the other voice) preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him.
I agree with you that the Bible isn't a failure. Men just need to Believe in the God which Speaks from it. And be "Doers" of the Word, like all the examples of those who Glorified God, and not just hearers, like Eve.
Great topic.
