The Bible indicates that God will not permit anything to happen that he can't use to bring ultimate good to his people and to glorify himself. That's his promise. Therefore, even the most terrible evil his children endure would not be pointless.
The essence of the quote from Randy Alcorn's book is that God's sovereignty ensures that everything occurs for a purpose, even amidst suffering. It underscores the belief that God can transform adversity into avenues for greater good and spiritual growth for His followers. His promise is that no situation is entirely in vain, suggesting a greater divine plan at work beyond human understanding.
This perspective provides comfort to those facing hardships, reassuring them that their struggles have meaning. It emphasizes trust in God’s ultimate authority and benevolence, highlighting that even the worst experiences can serve a higher purpose in glorifying God and benefiting His creation.
