What does the Bible say about extreme sin and extreme grace?

Extreme sin is showcased in the actions of Simeon and Levi, who executed vengeance on an entire city in a fit of anger and self-will, as noted in Genesis 34. Jacob, their father, recognized these traits and condemned their violent behaviors, calling them instruments of cruelty. In stark contrast, Jacob himself represents extreme grace, acknowledging his own deceitfulness and sinfulness while still referring to his own glory, which signifies God's grace towards him. Thus, the narrative illustrates the simultaneous existence of extreme sinfulness and the immense grace given by God, allowing flawed individuals to possess divine glory through faith.
