Jesus heals the sick and lame in the temple, and the Pharisees who were supposed to nurture Israel.....didn't.
Jesus compares the scribes and Pharisees to a son who said he would obey the father, but....didn't.
Jesus then compares the scribes and Pharisees to vineyard workers who were supposed to take care of their master's vineyard, but.....didn't.
So when a hungry Jesus looks for breakfast from a fig tree that was supposed to bear fruit but....didn't -
He cursed it. Call it the Sign of the Fig Tree. People, like trees, are called to bear fruit of compassion, obedience, and faithfulness. All we like fig trees have gone astray, but the Lord has laid on Him the iniquity of us all.
