God never wastes suffering, not a scrap of it. He redeems all of it for His glory and our blessing. The classic Biblical reference for the concept that suffering displays God's strength through our weakness is found in 2 Corinthians 12:8-10, where we learn that God's grace is sufficient for us, for His power is perfected in weakness. Paul said he delighted in weaknesses, hardships, and difficulties "for when I am weak, then I am strong."
Sometimes our suffering isn't a consequence of our actions or even someone else's. God is teaching other beings about Himself and His loved ones—us—as He did with Job. The point of Job's trials was to enable heavenly beings to see God glorified in Job. Sometimes He trusts us with great pain in order to make a point, whether the intended audience is believers, unbelievers, or the spirit realm.
Joni Eareckson Tada, no stranger to great suffering, writes, "Whether a godly attitude shines from a brain-injured college student or from a lonely man relegated to a back bedroom, the response of patience and perseverance counts. God points to the peaceful attitude of suffering people to teach others about Himself. He not only teaches those we rub shoulders with every day, but He instructs the countless millions of angels and demons. The hosts in heaven stand amazed when they observe God sustain hurting people with His peace."
