Luke 13:8

“And he answering says to him, “Lord, let it alone this year also, till I shall dig about it, and feed it with manure, and if it bear fruit from then on, well, and if not, you shall cut it down.”

The vinedresser then suggested that the fig tree be given one more chance to prove itself. He will turn over the soil around it and feed it with manure, Then if it produces fruit all will be satisfied, and if it does not then it can be cut down.

The parable is based on the same idea as lies behind John's words in Luke 3:9. The fig tree represents God's supposed people who should be fruitful. Over a complete period of three years (a period which is a sufficient and complete test) they had been tested and had not been fruitful. The warning is then of judgment to come because they are fruitless. The owner is probably God the Judge of all the world. The vinedresser is probably intended to be Jesus Who was here to nourish Israel and was giving them one last chance. The vinedresser's suggestion indicates that this is their last chance. If they remain fruitless they will perish. The words clearly indicate that He considers that the people have been given every opportunity, and are now being given their last opportunity. If the people still fail to respond to His teaching then only judgment awaits them, and He wants them to know that God is in full agreement with Him on the matter. If they will not be made straight then they will perish. It will be noted that parables of fruitfulness occur both sides of the story of the woman who was made straight, stressing that that story is to be seen as more than just a miracle story, but as an indication of God's purpose for His own, a making fruitful of His elect.
