What we mean by this is that suffering reveals things about God and His character that we wouldn’t know or experience otherwise. There are certain aspects of God’s character that would be unknown apart from an experience of evil and suffering. How would we know that God is compassionate if we never had a need? How would we realize that God is both just and justifier if there never was the evil of sin? How would we experience the comfort of God if we never felt loneliness, pain, or grief? How would we know that God as healer if there were no hurts?
