Amen! In Mormonism you have to earn eternal life; there is no other option. The reward is based on how many and which commandments you kept. For instance:
Eternal life and Exaltation are identical.
D&C 132
1–6, Exaltation is gained through the new and everlasting covenant;
7–14, The terms and conditions of that covenant are set forth;
15–20, Celestial marriage and a continuation of the family unit enable men to become gods;
21–25, The strait and narrow way leads to eternal lives;
26–27, The law is given relative to blasphemy against the Holy Ghost;
28–39, Promises of eternal increase and exaltation are made to prophets and Saints in all ages;
40–47, Joseph Smith is given the power to bind and seal on earth and in heaven;
48–50, The Lord seals upon him his exaltation;
51–57, Emma Smith is counseled to be faithful and true;
58–66, Laws governing plural marriage are set forth.
15 Therefore, if a
man marry him a wife in the world, and he marry her not by me nor by my word, and he covenant with her so long as he is in the world and she with him, their covenant and marriage are not of force when they are dead, and when they are out of the world; therefore, they are not bound by any law when they are out of the world.
16 Therefore, when they are out of the world they neither marry nor are given in
marriage; but are appointed angels in
heaven, which angels are ministering
servants,
to minister for those who are worthy of a far more, and an exceeding, and an eternal weight of glory.
17 For these angels did not abide my law; therefore, they cannot be enlarged, but remain separately and singly, without exaltation, in their saved condition, to all eternity; and from henceforth are not gods, but are
angels of God forever and ever.
18 And again, verily I say unto you, if a man marry a wife, and make a covenant with her for time and for all eternity, if that
covenant is not by me or by my word, which is my law, and is not sealed by the Holy Spirit of promise, through him whom I have anointed and appointed unto this power, then it is not valid neither of force when they are out of the world, because they are not joined by me, saith the Lord, neither by my word; when they are out of the world it cannot be received there, because the angels and the gods are appointed there, by whom they cannot pass; they cannot, therefore, inherit my glory; for my house is a house of order, saith the Lord God.
