This sermon invites believers to rediscover faith and trust in God’s promises, even when doubt and disappointment arise. Drawing from Sarah’s disbelief, Mary’s courage, and Peter’s obedience, it reminds us that God’s word never fails—but it calls for surrender and reliance on Him. Through a moving personal story of faith amid illness, the message urges listeners to repent of unbelief, seek prayer, and lean on spiritual family, affirming that God’s promises will surely come to pass.
