Over five hundred years ago, Christianity was buried under layers of superstition, immorality, and biblical illiteracy—yet questions about life and death, knowledge and authority, and how sinful men and women could be made right with God remained. In this Reformation Day message, Alistair Begg recounts how the church of medieval Europe came to rediscover the Gospel message found in Jesus' life and death. Through Martin Luther and others, the true significance and sufficiency of Christ's death was recovered, bringing reform to the church and the promise of salvation to all who trust in Him.
