In this sermon, Joshua Watkins explores the story from Mark 2, where Jesus calls Levi, a tax collector, to follow him. Watkins reflects on the significance of Jesus reaching out to regular, everyday people, including those considered sinners and outcasts by society. He emphasizes Jesus' approach of befriending and positively impacting those he encountered, rather than isolating himself from them like the Pharisees. Joshua encourages Christians to consider their own relationships and opportunities to be a positive influence on those who may not know Jesus, emphasizing the importance of showing love and being an example in their lives.
