D.L. Moody shares a touching story of a child who, with earnestness and simplicity, expressed her love for Jesus and encouraged a friend to love Him too. This innocent yet profound interaction moved an adult listener to reach out to someone in need of spiritual guidance for the first time. Moody emphasizes the powerful impact that children can have in leading others to Christ through their genuine faith and love. The sermon illustrates how the pure hearts of children can inspire adults to embrace their faith and share it with others. Ultimately, it reinforces the biblical truth that 'a little child shall lead them.'
