Boyd K. Packer has said in the talk
“Covenants,” “Ordinances and covenants become our credentials for admission into [God’s] presence” (par. 38). So without these sacred promises, we cannot be admitted into God’s presence. Not only that, but Covenants will give us that added blessing we need everyday. “Participating in ordinances and honoring the associated covenants will bring you marvelous light and protection in this ever-darkening world” ("
Saving Ordinances Will Bring Us Marvelous Light", par. 32). Covenants are not just required for our admittance into heaven, they are helpful in guiding us back to our Heavenly Father. Making these sacred promises will unlock the “door to every spiritual blessing and privilege available…” ("
A Message From the First Presidency", par. 3). It is going to be hard to overcome and withstand temptations, but God loves us and wants to help in any way He can.
