The Resurrection.

Because of Adam and Eve, we will all die, this is a promise that God gave them when they ate of the fruit of the tree of Knowledge of Good and Evil in the Garden of Eden. When they ate of it they would die in two different ways Physically and spiritually. Physical death is where our body is separated from our body. Spiritual death is separation of us from God. (Alma 42:9)

Because of Jesus Christ we will all be raised from both physical and spiritual death. The prophet Alma, in The Book of Mormon, explained to his son that Resurrection is when our body and spirit are joined together again, but our body will be made perfect.(Alma 40:23)

After we are resurrected, we will all be brought into the presence of God to be Judged of what we have done here on the earth, (Revelation 20:13-13)and we will be judged by Jesus Christ (John 5:22-23). As we will be judged according to our works, It seems a little unfair that God would have only two options, like If you make it this far you get to heaven, if you fall short you go to hell. And you do not need to accept Jesus Christ in order to be a good person, So what happens to them?

well, Lets first establish that there are more than two places that you can go, There is more than just heaven or hell. In 1 Corinthians 15 Paul is explaining to the Corinthians that there will be a resurrection, and in (1 Corinthians 15:40-42) Here it compares the types of body to the Sun, the Moon, and the Stars. This is what it refers to when we receive according to our works. 

Those who follow Jesus Christ, strive to keep his commandments and are Baptised will receive this "Glory" Now it dost mean they will become the sun but they can be compared to the sun. for example in Revelation 1:16 it compares the countenance of Jesus to the sun. Those who are compared to this glory will live with God, and they will live in a state of perfect joy and peace. I love how in psalms 16:11 it teaches that in Gods presence is a fullness of Joy. 

The glory of the Moon, Is for people who lived a good life, but for one reason or another chose not to follow Jesus Christ. They will have some amount of happiness. But they will not live with God, and as a result will never be as happy as those who have been cleansed through Jesus Christ.

The lowest of these three places is compared to the stars. Just as from our perspective the stars are almost nothing in compared to the moon, and you cannot even see them compared to the sun. The Glory of these people will be almost nothing. This is because they did not live good lives and did not want to change. God has prepared somewhere for them to live.

This was something that God revealed to Joseph Smith through divine revelation. And is one of the many fruits that God has given to us through prophets who live today.
