In our Heavenly Father’s plan of happiness, a husband and wife can be together forever. The authority to unite families forever is called the sealing power. It is the same power that Jesus bestowed upon His Apostles during His ministry on earth (see Matthew 16:19). An eternal marriage is therefore called a sealing, and children born or adopted into such eternal marriages can also be sealed to their families forever. Unlike marriages that last only “’til death do you part,” temple sealings ensure that death cannot separate loved ones. For marriage relationships to continue after death, those marriages must be sealed in the right place and with the right authority. The right place is the temple and the right authority is the priesthood of God (see Doctrine and Covenants 132:7, 15–19). https://www.youtube.com/watch?v=gA6aTiMDYho
