J.R. Miller emphasizes the profound challenge of truly loving our neighbors, as illustrated in the parable of the Good Samaritan. He contrasts the actions of the priest and Levite, who passed by a wounded man without offering help, with the Samaritan who showed compassion and took action. Miller argues that love is not merely the absence of harm but the active pursuit of doing good for others, highlighting that neglecting to help those in need is a serious moral failing. He calls on listeners to reflect on their own lives and consider how often they pass by opportunities to show love and kindness. Ultimately, Miller urges that we will be judged not only by our actions but also by our inactions towards those around us.
