The Jurassic Park aspect comes when the T-Rex is chasing the Jeep and the driver is able to go faster and provides the characters a way of escape from the creature that would tear them apart. The sin of bitterness is like that T-Rex looking to overtake and devour and destroy. As believers, we have the ability to resist temptation and sin. We should not want to be overtaken and eaten. We should want to flee and be free.
