The seal of the living God mentioned in Revelation 7:2 includes the Abrahamic Covenant,¹ which is called the new and everlasting covenant of marriage.² The Abrahamic Covenant is the fulness of the restored gospel of Jesus Christ,³ including all gospel ordinances⁴ beginning with baptism⁵ and ending with the sealing ordinance,⁶ which is often called eternal marriage.⁷ The sealing ordinance unites couples and families for time and eternity.⁸ To be exalted in the highest degree of glory in the celestial kingdom,⁹ men and women must be sealed as husbands and wives¹⁰ in the temple¹¹ and symbolically receive the seal of the living God in their foreheads.¹² The temple sealing ordinance is the gateway ordinance for men and women to be exalted as kings and queens¹³ in the highest degree of glory in the celestial kingdom.¹⁴ In that exalted state they become Gods¹⁵ with the power of eternal increase.¹⁶

When husbands and wives are worthily sealed in the temple,¹⁷ they enter the Patriarchal Order of the Priesthood.¹⁸ This priesthood order existed in the premortal spirit world,¹⁹ and it is perpetuated on earth²⁰ when husbands and wives are sealed in the temple.²¹ The sealing ordinance has the effect of sealing,²² welding,²³ or linking God's worthy children²⁴ together into one great family²⁵ in all their earthly²⁶ and heavenly generations.²⁷ Children born to husbands and wives that have been sealed in the temple are said to be born in the covenant.²⁸ These children receive all the blessings and spiritual protections²⁹ of the Abrahamic Covenant³⁰ based on their personal faithfulness.³¹ Children that are not born in the covenant can be sealed to their parents through the ordinance of adoption.³² In this way the sealing ordinance perpetuates the Patriarchal Order of the Priesthood among all sealed persons through all generations of time and eternity.³³ The Patriarchal Order will be the governing organization of God's kingdom in the millennium,³⁴ in the celestial kingdom,³⁵ and throughout the eternities beyond.³⁶

Husbands, wives, and family members that do not receive the sealing ordinance may qualify to enter the celestial kingdom,³⁷ but they will do so as unmarried individuals without family link.³⁸ They will not be exalted in the highest degree of celestial glory.³⁹ Baptism is the gateway ordinance⁴⁰ to enter the lowest degree of glory in the celestial kingdom.⁴¹ Baptism is not required for entry into the terrestrial and telestial kingdoms.⁴² Accountable persons that have died without an opportunity to accept the gospel can still be heirs of the celestial kingdom,⁴³ but they must accept the gospel in the spirit world and then vicariously receive baptism and confirmation by proxy.⁴⁴ In addition, they must be vicariously sealed to a spouse to be exalted in the celestial kingdom.⁴⁵

Unaccountable people in this life can enter the celestial kingdom when they are resurrected without the baptismal ordinance.⁴⁶ This includes those that die before the age of eight⁴⁷ and those with mental or other disabilities that limit their agency⁴⁸ in this life.⁴⁹ Through the mercy and atonement of Jesus Christ,⁵⁰ unaccountable persons can also be exalted without baptism.⁵¹ However, all unaccountable and unbaptized persons spoken of here must still receive the sealing ordinance by proxy to qualify for exaltation.⁵²
