JOEL - The one who stays faithful to the Gospel will not be denied the Celestial Kingdom for things beyond their control. The faithful divorced member will still inherit the Celestial Kingdom without their original spouse. We assume that such individuals wil be able to marry again, if not in this life, then perhaps during the Millennium, so that they will have an eternal companion.
President Ezra Taft Benson said:
"I recognize that some sisters are widowed or divorced. My heart is drawn to you who are in these circumstances. The Brethren pray for you, and we feel a great obligation to see that your needs are met. Trust in the Lord. Be assured He loves you and we love you. Resist bitterness and cynicism.
I also recognize that not all women in the Church will have an opportunity for marriage and motherhood in mortality. But if you in this situation are worthy and endure faithfully, you can be assured of all blessings from a kind and loving Heavenly Father—and I emphasize all blessings." (Ezra Taft Benson, “To the Single Adult Sisters of the Church,” Ensign, Nov. 1988, 96)
So even if your "opportunity for marriage" in this life is cut short by divorce, Heavenly Father will make sure you get "all" blessings you are entitled to.
