Matthew 5:42 Give to him who asks you, and from him who wants to borrow from you do not turn away.
And when the borrower will not be able to pay, you are prohibited to go to any court of law.
1 Corinthians 6:1 Dare any of you, having a matter against another, go to law before the unrighteous, and not before the saints?
You may ask, who are the saints? Unlike the Catholics where their saints must die first and be declared after, members of the Church of God are considered in the Bible as Saints.
1 Corinthians 16:1-2 Now concerning the collection for the saints, as I have given orders to the churches of Galatia, so you must do also: On the first day of the week let each one of you lay something aside, storing up as he may prosper, that there be no collections when I come.
Besides, how can a saint judge things that pertain to this life when he is already dead?
1 Corinthians 6:3 Do you not know that we shall judge angels? How much more, things that pertain to this life?
The Church is the proper venue. One believer must not sue another believer—right in front of unbelievers.
1 Corinthians 6:4 If then you have judgments concerning things pertaining to this life, do you appoint those who are least esteemed by the church to judge?
Let us therefore accept the injustice and leave it at that and let ourselves be cheated.
1 Corinthians 6:7 Now therefore, it is already an utter failure for you that you go to law against one another. Why do you not rather accept wrong? Why do you not rather let yourselves be cheated?
