I wonder why it is that death and time seem so important to people.
For one thing, we all face death and death marks the end of our mortal existence. Once death has entered the scene all things mortal have expired. All we have is time and it's quickly running out with each passing day.
What is important is truth.
Truth is important but not neccessary to survive. It's a luxury. If you think you know the truth you may consider yourself, lucky.
Truth does not change and can be written by anyone who knows what actually happened whether they were there or not.
Truth is also in the eye of the beholder. Everyone sees their own truth and how they perceive truth. Truth is open to debate in this mortal world. However, things like 2 + 2 will always be 4 no matter what anyone says. The fact that there is no king's name in Facsimile No. 3 is an established truth because the language says what it does just like my paragraph is telling you a message but it says nothing about ancient Chinese traditions.
The only issue is did the revelation come from someone who has access to the truth.
And if Joseph Smith was telling us the truth then Egypologists today would have told us the name of the Egyptian king in Facsimile No. 3 and confirm the other things Joseph claimed as revelation in the Explanations of the same.
Here faith comes into play and the witness of the Holy Spirit.
There are too many Latter-day Saints that have faith in Joseph Smith's Explanations of Facsimile No. 3 even though they have been shown to be untrue. Having faith in something that is untrue in the face of obvious lying is not healthy.
Not only does God declare truth to His servants but He gives the elect the ability to determine independently the truth of scripture.
Truth to god's servants? Let's elect you! Why did Joseph Smith call an Egyptian god a slave in Facsimile No. 3?
