The gospel message serves as a powerful light that illuminates spiritual darkness. Before encountering salvation, people view life through a distorted lens that affects their perspective on relationships, work, and identity. God breaks through this darkness by shining His light into hearts, revealing His glory and the path to salvation. He purposefully uses ordinary, imperfect people as vessels to carry His message, allowing their vulnerabilities and past struggles to become powerful testimonies that connect with others who are searching for truth.
