J.R. Miller addresses the dangers of overindulgence in parenting and education, arguing that kindness can sometimes lead to unkindness by preventing children and students from facing challenges and hardships necessary for growth. He emphasizes that true kindness involves allowing individuals to endure difficulties, as this fosters resilience and character. Miller illustrates that God's love is not indulgent but rather involves discipline and the allowance of pain for the sake of spiritual growth. He warns that the modern tendency to avoid discomfort can lead to failure in preparing the younger generation for life's struggles. Ultimately, he calls for a balance between kindness and the necessity of hard lessons, drawing parallels to the sacrifices made by artists in pursuit of their ideals.
