Going to court or suing someone seems like a moot point, and possibly even a waste of time, if God is going to settle all matters in the end, as justice is served by God. So why waste years or months of your time in court if you believe in God’s justice? Isn’t court a secular way of serving justice?
As an atheist, I tend to agree with you. But aren’t we atheists always finding inconsistencies in Christian beliefs and behaviour, mainly to make ourselves feel better? Not without reason, of course. We are admonished constantly by the Christians themselves how much better we would be as human beings if we believed in their God so obviously we do see the double standards and hypocrisy of Christianity.
Sometimes I think that people who depend on God to fix their problems don’t learn how to do it themselves. Possibly that is one reason they need the courts so badly. Why they can’t wait for God’s judgment…well, they’re only human and humans can always make excuses to get what they want. It is human to want what we want NOW! Not to mention that the ability to wait for delayed gratification is a sign of maturity.
I’m not sure how good an answer this is. Maybe not even worth letting it stand. Sorry, it’s the best I can come up with at the moment.
