"Rabbi," his disciples asked him, "why was this man born blind? Was it because of his own sins or his parents' sins?" "It was not because of his sins or his parents' sins," Jesus answered. "This happened so the power of God could be seen in him."
John 9:2-3 , NLT
A common belief in Jewish culture was that calamity or suffering was the result of some great sin. But Christ used this man's suffering to teach about faith and to glorify God. We live in a fallen world where good behavior is not always rewarded and bad behavior not always punished. Therefore, innocent people sometimes suffer. If God took suffering away whenever we asked, we would follow him for comfort and convenience, not out of love and devotion. Regardless of the reasons for our suffering, Jesus has the power to help us deal with it.
When you suffer from a disease, tragedy, or disability, try not to ask, "Why did this happen to me?" or "What did I do wrong?" Instead, ask God to give you strength for the trial and a clearer perspective on what is happening.
