Why doesn’t God swoop down and show us that he is real? Surely everyone would believe if he did that! Jesus shows that it does not work that way. The people of Israel saw the miracles but still refused to believe.
In this story, Jesus heals the son of a Roman official. However, at the beginning of the story the man sought Jesus just for the sake of a miracle. As the story goes along, his faith progresses to where he truly believes in Jesus for who he is. He saw beyond the miracle to have faith in the person who did the miracle.
