1 Cor 6:5-8
5 I say this as bluntly as I can to wake you up to the stupidity of what you're doing. Is it possible that there isn't one levelheaded person among you who can make fair decisions when disagreements and disputes come up? I don't believe it. 6 And here you are taking each other to court before people who don't even believe in God! How can they render justice if they don't believe in the God of justice?
7 These court cases are an ugly blot on your community. Wouldn't it be far better to just take it, to let yourselves be wronged and forget it? 8 All you're doing is providing fuel for more wrong, more injustice, bringing more hurt to the people of your own spiritual family.

It is indeed an ugly blot when "Jesus name" people subject His name to disrepute before unbelievers. It's amazing that we have enough faith to believe that He will save us, but we don't believe that He will vindicate us if our cause is right.
