This sermon explores the concept of collateral damage resulting from personal sin, using the narrative of Achan in Joshua 7 as the primary framework. The message outlines three key aspects: the route of sin, which begins with coveting and ends in shame and death; the reach of sin, which extends beyond the individual to affect family, church leadership, and the broader community; and the remedy for sin, which involves humility, confession, restitution, and a commitment to holy living. The preacher emphasizes that while God offers forgiveness, the lingering consequences of disobedience can still impact relationships and spiritual standing. Believers are urged to take sin seriously, flee from temptation, and actively pursue righteousness to protect themselves and those around them from the destructive effects of unconfessed sin.
