After Jesus radically cleansed the Jerusalem Temple by driving out the thieves that were there, he came to a fig tree because he was hungry. Unfortunately, the fig tree was not producing any figs at this point in time. In a bizarre twist in the story, Jesus condemns the barren tree and it begins to wither. What is even more confusing about this story is that Jesus never explains it.
This is what most people today believe happened with this tree: Jesus was condemning the current Jerusalem for producing the fruit of righteousness that God desired. The story has basically nothing to do with the tree itself; it was a prophetic condemnation on Israel for not doing what God wanted them to do. They were simply going through the motions of their religious practice, and lacked what they truly needed: a love for their God, and a love for the people around them.
We do not want to be condemned by Jesus for not “bearing fruit”. We need to make sure that we are producing the fruit of the Spirit (Galatians 5:22-23) in our lives, and “being Jesus” to the rest of the world. We need to act as faithful stewards of the grace that has been given to us. We need to be “good trees”, producing fruit that God would be proud of.
