Similar to the situation with Lazarus, our primary role as followers is to bring glory to God with our lives, regardless of whether or not we’re dealing with disease or sicknesses. And furthermore, there might be times when God orchestrates sickness, or even things like blindness, as a part of His plan to bring Him glory.
