Absurd Scenarios in Ether

Ether 3:25; “And when the Lord had said these words, he showed unto the brother of Jared all the inhabitants of the earth which had been, and also all that would be; and he withheld them not from his sight, even unto the ends of the earth.”

2 Timothy 4:3-4; “For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears; 4 And they shall turn away their ears from the truth, and shall be turned unto fables.”

Really? What purpose did this serve and what does it serve for the individual Mormon today?
