This chapter ends with Jesus’ authority being called to question. He, however, asserts his authority well before.
When Jesus curses the fig tree, He is cursing Israel at large and specifically the temple and religious establishment.
The fig tree has parallels to Israel and figs are carved into the paneling in the temple. Jesus cursing it tells the disciples that God is done with that system. Further, Him clearing it out states the same thing and gives people context for God’s plan. He wants people to be able to access Him and the plan was always for relationship with Him. Do you believe that? Do you have one?
