Ordinances are rites administered by the authority of the priesthood. “Some ordinances are essential to our exaltation. These ordinances are called “saving” ordinances. They include baptism, confirmation, ordination to the Melchizedek Priesthood (for men), the temple endowment, and the marriage sealing. With each of these ordinances, we enter into solemn covenants with the Lord.” (True to the Faith, p. 109)
The purpose of ordinances is to provide comfort and guidance for faithful Mormons. However, receiving the benefits from the ordinances can only come through obedience. Mormons receive strong encouragement to remember their duty and obligations associated with their covenant promises made at every ordinance. When they honor these ordinances with sincere effort, only then will the Holy Ghost provide strength to be obedient to them.
