This sermon explores the account of Achan, who secretly took forbidden items during the conquest of Jericho, leading to devastating consequences for the entire nation of Israel. Through this story, we learn that sin always begins with a compromised heart, hidden sin produces wider consequences than we expect, and the path back to God's favor requires confession and holiness. The message challenges us to examine what we're allowing our eyes to linger on, consider who would be affected if our hidden life became public, and take steps of obedience that God is calling us to today.
