What does the Bible say about exceptions to God's justice?

The Bible delineates that while God's rule of justice is absolute, there are exceptions which are solely in the capacity of God through Christ. For instance, John 3 emphasizes that to enter the kingdom of God, one must be born again, which is a divine exception to the rule that establishes the wages of sin as death (Romans 6:23). Additionally, Luke 13:3 reiterates this by calling for repentance as a prerequisite for salvation, emphasizing that mercy and grace manifest as the exceptions to the justice which our sins warrant.
