Zac Poonen emphasizes the transformative power of the Word of God, illustrating its effects through various metaphors such as light, mirror, fire, hammer, seed, food, dew, wealth, and sword. He explains how the Bible guides believers through darkness, reveals their true spiritual condition, purifies their lives, breaks down obstacles, and nourishes their souls. Poonen encourages regular engagement with Scripture to experience its blessings and strength, highlighting that neglecting the Word leads to spiritual weakness. He concludes by reminding the congregation that the Word equips them to face life's challenges and to grow in faith.

William MacDonald emphasizes the power and effectiveness of the Word of God, illustrating how it is living and active, capable of penetrating hearts even when met with disbelief. He recounts a story of a Christian student who felt defeated when witnessing to a skeptic, only to receive encouragement from Dr. H. A. Ironside, who advised to simply quote more Scripture. MacDonald argues that the Bible, like a sword, does not need defending but should be wielded confidently, as it can bring conviction and transformation. He stresses the importance of memorizing Scripture so that it can be readily available for the Holy Spirit to use in moments of witnessing. Ultimately, he reminds us that God honors His Word, and it is through the Scriptures that true change occurs in people's lives.
