Luke 3:1-5

When we come to the realization that we cannot save ourself, repent of our sins and seek Him we will find Him. God is on your side, He shows no partiality and He wants no one to perish. Believe in the salvation that only He could provide and you will be saved.

Jesus’ question reflected the opinion of His audience. The idea that judgment and death are the results of sin led to the belief that tragic death was the result of extreme sin. While such a view was common in Judaism, it was not always a correct conclusion. Jesus’ point here is that everyone stands at the edge of death until repentance occurs. The death in view here is spiritual, not physical. 

Luke 3:1-5

13 There were present at that season some who told Him about the Galileans whose blood Pilate had mingled with their sacrifices. ² And Jesus answered and said to them,  “Do you suppose that these Galileans were worse sinners than all other Galileans, because they suffered such things? ³ I tell you, no; but unless you repent you will all likewise perish. ⁴ Or those eighteen on whom the tower in Siloam fell and killed them, do you think that they were worse sinners than all other men who dwelt in Jerusalem? ⁵ I tell you, no; but unless you repent you will all likewise perish.”
