Smith Wigglesworth emphasizes that faith is the only way to access the treasures of God, urging believers to approach Him through the open door of grace. He illustrates the importance of faith through biblical examples, contrasting the zeal of the praying crowd for Peter with Rhoda's unwavering belief, and highlighting the faith of Mary compared to Zacharias' doubt. Wigglesworth encourages a deep, supernatural faith that transcends natural limitations, asserting that true faith is a gift from God that empowers believers to experience His promises. He calls for a life of obedience and communion with God, where believers can walk in the Spirit and be transformed by faith. Ultimately, he invites the congregation to embrace a fuller experience of faith and power in their lives.
