activate the power

Sheri L. Dew: [T]he Lord is our advocate, and He “knoweth the weakness of man and how to succor them who are tempted” (D&C 62:1). In other words, He knows how to succor all of us. But we activate the power of the Atonement in our lives. We do this by first believing in Him, by repenting, by obeying His commandments, by partaking of sacred ordinances and keeping covenants, and by seeking after Him in fasting and prayer, in the scriptures, and in the temple.
