Suffering as a method of discipline
One of the reasons God allows suffering in the lives of His children is that He desires to draw our attention to Himself, to correct and discipline us. We know that God mostly corrects us by His Word: «All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work» (2 Timothy, 3:16-17).
