How dis you say that? When we are suffering with a sickness, disease, or injury, we usually focus solely on our own suffering. In the midst of a trial of sickness, it is very difficult to focus on what good God might bring about as a result. In Romans 8:28 And we know that for those who love God all things work together for good, for those who are called according to his purpose. This verse help you to understand and to reminds us that God can bring about good from any situation. Many people look back on times of sickness as times when they grew closer to God, learned to trust Him more, and/or learned how to truly value life. This is the perspective God has because He is sovereign and knows the end result.This does not mean sickness is always from God or that God always inflicts us with sickness to teach us a spiritual lesson. In a world tainted by sin, sickness, disease, and death will always be with us. We are fallen beings, with physical bodies prone to disease and illness. Some sickness is simply a result of the natural course of things in this world. Sickness can also be the result of a demonic attack. The Bible describes several instances when physical suffering was caused by Satan and his demon, So, some sickness is not from God, but from Satan. Even in these instances, God is still in control. God sometimes allows sin and/or Satan to cause physical suffering. Even when sickness is not directly from God, He will still use it according to His perfect will. Maybe this passage can help to change your mind.
