Essential to God’s great plan for the mortal growth of His children was for them to experience “opposition in all things” (2 Nephi 2:11). Just as our physical muscles cannot be developed or maintained without straining against the law of gravity, so mortal growth requires us to strain against Satan’s temptations and other mortal opposition. – Dallin H. Oaks, “Divine Helps for Mortality,” Liahona (CR) May 2025
