Samuel Logan Brengle emphasizes that God is the ultimate source of spiritual power, which can be accessed through meditation on His word and secret prayer. He recounts an encounter with an Ensign who underestimated the importance of dedicating time to Scripture study, suggesting that many desire spiritual strength yet neglect the means to obtain it. Brengle warns that without consistent prayer and meditation, individuals risk spiritual weakness and eventual death. He encourages believers to prioritize time with God, asserting that this devotion is essential for spiritual growth and strength. Ultimately, he assures that through quiet communication with God and attentive listening to His word, peace and power can be restored.
