Robert Constable reflects on the story of the Road to Emmaus, emphasizing the need for burning hearts among believers. He highlights the disciples' despair and loss of passion after Jesus' crucifixion, noting that while they remembered His deeds, their enthusiasm had waned. Constable urges the church to rekindle its fervor for Christ, reminding that true passion comes from listening to Jesus and understanding His message. He encourages believers to seek a deeper connection with Christ, which can reignite their faith and enthusiasm for service. The sermon calls for a revival of passion in the church, akin to the disciples' hearts burning as Jesus spoke to them.
