Those who are worthy to return to God's presence can continue to progress towards attaining a fullness of God's glory, which is referred to as eternal life, or exaltation (Doctrine and Covenants 76).
Those who are worthy to return to God's presence achieve the highest glory, which Paul compared to the sun (1 Cor 15:40-41). These are they who can inherit a fullness of God's glory, because they have no limit to their progression (Doctrine and Covenants 76).
