When one of the parties reject the opportunity to be reconciled to God's TRUTH (Jesus, mercy, forgiveness and love) because they want the world's perspective of truth and it's system of harsh justice to rule their diffferences. Then the other party as well has to enter into the world's system to bring solution to the conflict. The only difference here is that the person that rejected the opportunity to take the conflict to the saints for reconciliation has dared God as it states in 1 Corinthians 6:1 and defrauded his brother of the justice of God. and lost the GRACE of God and His mercy and God actually intervines and judges the unbelieving person as if he were his enemy.
Let's be Reconcilers and not Judges
