The warnings and admonitions regarding the coming judgement that began in 12:1, reach their conclusion here with a call to repentance.
Jesus uses two sayings to make the same point. The first is about the calamity that occurred when Pilate slaughtered a group of Galileans and when the tower of Siloam fell and killed eighteen people. Though no other historical reports narrate these incidents, there may be some historical background to the first one, Josephus the Jewish historian does narrate many incidents, which confirm that Pilate shed much blood.
In the incidents that Jesus narrates, however, he makes clear that what is required on the part of the human person is not the focus on sin and its consequences but on repentance, which means the acquisition of a new mind, a new heart and a new vision.
Near Eastern wisdom literature contains stories of unfruitful trees and the story of the barren fig tree is similar to the stories found there. While in the story as told by the Lucan Jesus there is mercy, it is still a warning of the urgency of repentance.
Each new day brings with it new hope and a new opportunity to right the wrongs that we may have done, to say the kind word that we ought to have said and to do the good that we ought to have done.
