And where do the Mormons get this theology. Is it from another great revelation that has come to mankind after thousands of years of the inspired, God breathed scriptures that have been followed as the one and only true word of God for over 2000 years? Is this "new" book of theology from man or from God. Did God mention that He would send more scripture? Or, is this just some man pretending to be some chosen messenger for some things God forgot to tell us. Or that God has changed His mind?
I think not. I don't adhere to anything that is from some new revelation to some self proclaimed chosen man or woman.
Actually it's not in the Book of Mormon but in the Bible. Paul in Cor 15 is explaining the resurrection and what will happen. In Mormon doctrine by the time a sinful man is resurrected he will have bowed his knee to Christ for 'every knee will bow' eventually and he will be in a forgiven state. Now it is time for his reword, it's on the premise that all men do some good
"...and they were judged every man according to their works." Rev 20
and they will be rewarded for that good no matter how small it may seem to us, and our Father never stops loving us.
37 And that which thou sowest, thou sowest not that body that shall be, but bare grain, it may chance of wheat, or of some other grain:
38 But God giveth it a body as it hath pleased him, and to every seed his own body.
Remember that in in Galatians he taught
"...for whatsoever a man soweth, that shall he also reap. For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting. And let us not be weary in well doing: for in due season we shall reap, if we faint not. Gal 6
40 There are also celestial bodies, and bodies terrestrial: but the glory of the celestial is one, and the glory of the terrestrial is another.
41 There is one glory of the sun, and another glory of the moon, and another glory of the stars: for one star differeth from another star in glory.
42 So also is the resurrection of the dead.
Each of us will be resurrected according to the glory we are worthy of and where we will be most happy. Where we go is really our own choice and we choose by our actions.
In Mormon theology there is no actual hell or lake of fire, we believe this is merely figurative of God's anger and our own shame at our rebellion. There is what we call the spirit prison as Peter mentioned. If a person has accepted Jesus and was a faithful servant upon death his spirit goes into paradise, a place of rest. They will be resurrected to a celestial glory.
If a person did not receive a chance to hear of Jesus during their time on earth they go to sort of a holding place where they are taught the gospel and are given a chance to bow their knee to Christ to receive of his grace and mercy. It is felt that most people will willing and gladly accept the Savior. Their reword will be between the celestial and terrestrial kingdoms depending on their hearts. A Hindu woman who learns Christ like love and served the people around her has as much opportunity to enter the Celestial kingdom as anyone.
And then there are those who rejected Jesus in this life, they will suffer for their own sins by remembering each and everyone. They will suffer the pains of a damned soul until the last farthing is paid. Then they will be resurrected and receive the glory of the Telestial Kingdom which is suppose to be much like this earth but without the pain and suffering.
