Over and over again, God's people have invited foreign influences into their hearts and homes, embracing the "slow stain of the world." From the Israelites at Sinai, to the early Christians in Rome, to the Saints in Missouri, the scriptural record is brimming with cautionary tales of covenant communities undone by worldly temptations. Yet we are not helpless spectators to these tragedies; we have the power to learn from their mistakes and guard ourselves against the subtle pull of false ideas and misguided practices.

In this penetrating exploration, Connor Boyack delves deeply into the historical and scriptural accounts of God's covenant people-tracing how each was gradually corrupted by outside influences and undone by pride, greed, or complacency. Readers will discover how those same destructive forces operate today and how we ought to counteract their spread in order to remain faithful to Jesus Christ.
