Leonard Ravenhill delivers a powerful sermon on Judges 18, emphasizing the question of how much one can lose without losing faith in God. He reflects on the story of Micah, who lost his gods and priest, and challenges the congregation to consider their own attachments and the fragility of worldly possessions. Ravenhill highlights the importance of inner faith and the assurance that true treasures, such as faith and peace, cannot be taken away by external circumstances. He encourages believers to cultivate gratitude for their blessings and to recognize that true maturity in faith comes through trials and tribulations. Ultimately, he calls for steadfastness in faith, regardless of life's challenges.
