Discuss the matter privately first
Proverbs 25: 8 don’t be in a hurry to go to court. You might go down before your neighbors in shameful defeat. 9So discuss the matter with them privately.
Christians going to court against each other is a bad testimony to non-believers
(1 Cor 6:5-7 NIV) I say this to shame you. Is it possible that there is nobody among you wise enough to judge a dispute between believers? {6} But instead, one brother goes to law against another–and this in front of unbelievers! {7} The very fact that you have lawsuits among you means you have been completely defeated already. Why not rather be wronged? Why not rather be cheated?
If you are in the wrong, try to settle the matter without having to go to court
(Mat 5:25-26 NIV) “Settle matters quickly with your adversary who is taking you to court. Do it while you are still with him on the way, or he may hand you over to the judge, and the judge may hand you over to the officer, and you may be thrown into prison. {26} I tell you the truth, you will not get out until you have paid the last penny.
In Jesus’ day, someone who couldn’t pay a debt was thrown into prison until the debt was paid. Unless someone came to pay the debt for the prisoner, he or she would probably die there. It is practical advice to resolve our differences with our enemies before their anger causes more trouble. (Source: Life Application Bible)
