Most Mormons and even some non-LDS know that Joseph Smith had a vision regarding the multiple kingdoms awaiting us after this life. Some Mormons know that Sidney Rigdon experienced the same vision with Joseph, probably to fulfill the law of witnesses. This vision came as a direct result of Joseph's efforts to correct the Bible, and Sidney's assistance as scribe. The two men came upon John 5:29 concerning the resurrection of the just and the unjust and decided the ask the Lord if Christianity was correct in its idea of 2 possible results for all people---Heaven or Hell.
GOD would obviously not be fair if there were some arbitrary cut off line dividing the sheep from the goats. Imagine the line was 50.1 percent goodness or righteousness and everyone from 50.0 percent down went to Hell. People who just missed the cut off would spend eons justifiably crushed at just missing out on the only good outcome. It is also patently unfair to put someone who is barely half good with others who could be 70, 80, or 90 percent good.
The Most High GOD is Not arbitrary so there are multiple kingdoms. There are 4 main divisions according to this vision: Celestial, Terrestrial, and Telestial Kingdoms, alone with Outer Darkness, a kind of permanent Hell.
The Telestial Kingdom and Outer Darkness fall under the "resurrection of the unjust" and all who end up in those 2 undesirable spots will spend time in Hell either temporarily (Telestial) or permanently (Outer Darkness). The top 2 kingdoms are part of the "resurrection of the just" and the blessing of such an outcome is CHRIST paying for your sins, and you getting to skip Hell altogether.
JESUS revealed to Joseph and Sidney the kind of people who end up in the lowest kingdom of glory in verse 103 of section 76 of the Doctrine and Covenants.
"These are they who are liars,
and sorcerers, and adulterers, and whoremongers,
and whosoever loves and makes a lie."
(I added the underlining for emphasis)
It looks like CHRIST is emphasizing the lying part because "liars" leads off the verse, and "a lie" ends it with nifty inclusio.
The line "whosoever loves and makes a lie" has always perplexed me, but now I think I have an answer. The line refers to anyone who uses deception to take away other people's free agency. It refers to anyone who enjoys lying for the sake of personal gain at the expense of others.
Now, who in the present day world who fit such a bill?
Politicians. The old joke about the politician being told he was lying and responding "I know I am, but hear me out!" comes to mind. Regardless of party, if you are just going with the flow of public opinion, and you do not stand up for truth and the rule of law, you are going to Hell.
Journalists. The media world-wide is so corrupt as to be a cruel joke. Promoting fear and hoping for rewards from their political overlords is just another great way to pay for your own sins with some wailing and gnashing of teeth.
Religious Leaders. No surprise here. Since the days of JESUS, religious leaders care more about power and prestige than people. They would rather kill the GOD of this world and forfeit salvation, than give up power. Still true today.
There should be a special section in the Telestial Kingdom for Sadducess, Pharisees, Molesting Priests, and pretend Apostles who have never seen GOD.
JESUS is real, and He has revealed to 2 of his servants that there are more than just Heaven and Hell. He also graciously gave them, and us, information about how to avoid the lowest kingdom:
be faithful to your spouse,
the occult is out,
avoid jobs in the sex industry, and...
