Luke 13:1-9

1 At that very time there were some present who told Jesus about the Galileans whose blood Pilate had mingled with their sacrifices.2 [Jesus] asked them, "Do you think that because these Galileans suffered in this way they were worse sinners than all other Galileans?3 No, I tell you, but unless you repent you will all perish as they did. 4 Or those eighteen who were killed when the tower of Siloam fell on them—do you think that they were worse offenders than all the other people living in Jerusalem? 5 No, I tell you, but unless you repent you will all perish just as they did." 
 
  6 Then he told this parable: "A man had a fig tree planted in his vineyard, and he came looking for fruit on it and found none. 7 So he said to the man working the vineyard, 'See here! For three years I have come looking for fruit on this fig tree, and still I find none. Cut it down! Why should it be wasting the soil?' 8 He replied, 'Sir, let it alone for one more year, until I dig around it and put manure on it. 9 If it bears fruit next year, well and good, but if not, you can cut it down.' "
