What does the fig tree symbolize in Matthew 21?

In Matthew 21:19, Jesus encounters a fig tree that is full of leaves but bears no fruit, which serves as a poignant metaphor for religious individuals or groups that present a facade of godliness without true spiritual substance. This imagery illustrates the judgment that falls upon those who have the appearance of faith but lack the genuine fruits of the Holy Spirit. The fig tree signifies a warning about the dangers of mere outward religiosity devoid of real life and fruitfulness, echoing the accountability of all who profess faith without corresponding actions.
