Christ discussed incidents where a tower collapsed and killed many people, and where the tyrant that ruled over them murdered them and used their blood to pollute their sacrifices. Christ warned us not to assume that victims of tragedy are necessarily greater sinners. Israel, and indeed most people today, assume that God blesses the righteous, and so the greater the tragedy, the greater the sin must be. This was the false view for which Job's friends were rebuked. They falsely insisted that God would not have allowed the tragedies experienced by Job, unless Job had committed some secret iniquity against the Lord. Some tragedies, the Lord Jesus instructed us, are warnings of judgment to come for unrepentant sinners. Judgment is sure to fall against the wicked. Rather than speculate about why tragedy falls on other people, we are to realize our own wickedness is sure to be punished one day. Christ assures us that something bad will happen because of our sin, and we ought to seek repentance and forgiveness from the Lamb Who was slain for our crimes. But His disciples couldn't grasp the truth of this, and when they came upon a man born blind, they assumed that either he or his parents had committed some grave sin. But Jesus set them right: sin in that case had nothing to do with it, but tragedy befell the poor man so that the works of God might be seen in him. Indeed, shortly thereafter, Christ performed the great miracle of giving sight to that poor man who was born blind! Nothing like that had ever been seen before! This was a great work given to Christ by His Father, to testify to His bona fides, that Jesus has all the power of God, because He is God!
