In this sermon, the speaker shares a powerful testimony of a young man who boldly shared his faith in a village plaza, leading to 43 people coming to Christ. The church in Lima had experienced a decline and realized the need for a change, leading them to prioritize evangelism. Despite facing opposition and apathy, they were determined to reach out to those around them. The speaker also mentions a Texan businessman who had a contract with the Peru government to clear jungle areas and build a town. The sermon emphasizes the importance of an extensive exposition of the Word and the need for churches to defend themselves against false teachings.
