Sealing
Heavenly Father’s plan of happiness is ultimately to have you and your family live with Him forever. The scriptures call the authority to unite families forever the “sealing” power. This is the same authority Jesus gave the Apostle Peter to provide blessings on earth that will continue in heaven “And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.” (Matthew 16:19) In sealing rooms within the temple, marriages between a man and a woman are performed. There, a man and a woman kneel and join hands across an altar to be married for this life and for eternity. During the ceremony, the officiator (called a temple sealer) asks the couple to confirm their commitment to each other and to God. They are promised an eternal union and other blessings that enrich the divine potential of the relationship. https://www.lds.org/temples
