There are three heavens in your religion. Non-Mormons who don't accept your religion can't be in Heavenly Father's presence. They are banished to one of the lower kingdoms.
Doctrine and Covenants 132
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.
"Immortality connotes life without end. Eternal life, on the other hand, connotes quality of life — exaltation, the highest type of immortality, the kind of life enjoyed by God himself. It is in the attainment of eternal life, which man must
earn in mortality, that he reaches his full potentiality."
Marion G. Romney of the First Presidency, General Conference, October 1978, Ensign, November, 1978, p. 14
"In order to qualify for exaltation in the celestial kingdom, we must gain the trust of the Lord here on earth. We gain the trust of the Lord through
earning it, and that is accomplished through our actual performance in living His [Mormon]gospel and keeping our covenants. In other words, we
earn the trust of the Lord by doing His will."
Richard J. Maynes, “Keeping Our Covenants,” Ensign, Nov. 2004, 92
“The Lord will judge each individual case and will assign transgressor to that degree to which each is entitled according to his works. If a man only merits a place in the telestial, that will be his reward; if it should be the terrestrial, then he shall be admitted to that kingdom. In order to enter the celestial a man must be true and faithful to the end, observing all things which the Lord has commanded, otherwise he shall be assigned to some other kingdom, or to outer darkness if his sins so merit.”
Joseph Fielding Smith, Doctrines of Salvation 3:310
“Also in the spirit prison are those who rejected the [Mormon]gospel after it was preached to them on earth or in the spirit prison. These spirits suffer in a condition known as hell. They have removed themselves from the mercy of Jesus Christ, who said, ‘Behold, I, God, have suffered these things for all, that they might not suffer if they would repent; but if they would not repent they must suffer even as I; which suffering caused myself, even God, the greatest of all, to tremble because of pain, and to bleed at every pore, and to suffer both body and spirit’ (D&C 19:16-18). After suffering in full for their sins, they will be allowed, through the Atonement of Jesus Christ, to inherit the lowest degree of glory, which is the telestial kingdom.”

Constantly skimming over the details isn't helpful to those non-Mormons who want to learn what Mormonism actually teaches.
