Heaven

One of the biggest differences between the LHMM and mainstream churches is the idea of who goes to heaven. Present day LHMMers do not believe that they have the opportunity to go to heaven. They believe that time has passed and a limited number of people (144,000) and some others (in a group called the Great Company) already have been selected for this reward.

The number of the 144,000 comes from three scriptures (NIV):
Re 7:4 Then I heard the number of those who were sealed: 144,000 from all the tribes of Israel.
Re 14:1 Then I looked, and there before me was the Lamb, standing on Mount Zion, and with him 144,000 who had his name and his Father’s name written on their foreheads.
Re 14:3 And they sang a new song before the throne and before the four living creatures and the elders. No-one could learn the song except the 144,000 who had been redeemed from the earth.
Wikipedia has a pretty good explanation. http://en.wikipedia.org/wiki/144,000

This term "144,000" is used to refer to The Church. Other terms for the same group are Little Flock and those that tried out for the High Calling.
LHMMer appeal to a Present Truth article that offered "88 proofs" that the High Calling was closed and ended. These "proofs" are actually more of indications. None of them are plain or easy to understand. Most of the logic involves a prior belief that the antitypes shown are true and then a mental jump is required to get the date.

Sometimes they appeal to an argument from Mt 7:14 "But small is the gate and narrow the road that leads to life, and only a few find it." and say that this shows that few would go to heaven. The number of all Christians in the world today could be defined as few in comparison to the entire world population. According to some sources Christians of all denominations make up only 33% of the world today and it is dropping while other religions such as Islam are growing. How do you define few?

Some LHMMers argue that you can see the faithfulness of those that had the opportunity to go to heaven because of the amazing trials they experienced that we do not have today (example martyrs who died for their faith, etc.) This is a view that is not up-to-date or uniformed.
"Modern-day persecution is well documented, despite some reports to the contrary. In fact, it is estimated that more Christians were martyred in the 20th Century than in the prior 1,900 years combined." http://www.persecution.com/

Here are some issues with the LHMM teaching about heaven:
1. Revelation is a book of symbols. Why does this number (144,000) suddenly become literal and refer to an actual limited number of people that have the opportunity to go to heaven?
2. The concept of a limited number of people in heaven is based heavily on Bible chronology and the time period WHEN that opportunity is available. Since there are major problems with the chronology, it doesn’t hold true.
3. Dividing people into classes of those that are more or less faithful and who will receive greater or lesser rewards from God is not helpful. It encourages separation, pride, and spiritual abuse because some people are considered more important than others. There is no reason why we should need to know the kind of reward that God gives us. It can mainly have harmful effects one way or the other.
4. What about the Great Company? It is also a heavenly class and the only reason they believe it is closed is because Jolly said he was the last one. If he wasn't the last one, then there could be a lot more people going to heaven according to their own teachings.
5. How do you define heaven? If the future presents "a new heaven and new earth" then where will those that have believed in Jesus as their Savior spend eternity? Is a new restored earth a "part of heaven" that Christians could enjoy as well?
Maybe we have to leave some of the details in God's hand. The Bible doesn't specify so we don't really know. It is possible.
2Pe 3:13 Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.
Re 21:1 And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea.
Isa 65:17 For, behold, I create new heavens and a new earth: and the former shall not be remembered, nor come into mind.
