Testimony as Spiritual Weapon in the War of Heaven, BYU–Hawaii Devotional Emphasizes Faith

At a BYU–Hawaii devotional, General Authority Seventy Elder Ronald M. Barcellos described the war in heaven as a battle of beliefs and urged students to strengthen their testimonies as a powerful weapon against Satan. He explained that a testimony is a gift confirmed by the Holy Ghost and emphasized seeking revelation through prayer, study, and action. The talk encouraged recommitting to Jesus Christ, with promises of divine guidance, peace, and joy as one’s faith grows.
