How do we know that God's condemnation is just?

God's condemnation is just, as affirmed in passages like Revelation 20:11-12, where judgments are based on works. The Lord's nature encapsulates justice; therefore, His condemnation commands righteousness. Romans 9:14-16 emphasizes that mercy and hardening are rightfully God's prerogative, and every question regarding His fairness stems from man’s limited understanding. The righteous judgment of God stands firm against all human attempts to challenge it. In essence, condemnation reflects God’s perfect justice and is applied based on our sins, not arbitrary election.
