If everyone lived their lives according to "what would Jesus do" could society function, or would it collapse?
Personally, I think it would improve but perhaps I'm being naive?
If everyone did what Jesus wanted
1- Everyone would plan ahead and work hard.
2- There would be no crime. No need for a police department.
3- There would be no poor through a combination of personal hardwork and voluntary donations from those who have more. No need for any type of government welfare.
4- Nobody would start a war. No need for the military.
5- No sex out of marriage, so no unwanted pregnacy, so no abortion. No need for laws to regulate any of this.
6- No kids without parents, who love and care for them. In the case of death or unfortunate circumstances a family member would step in.
7- No divorce because nobody would do anything bad enough to make the other party seek a divorce.
8- No violence in society. No fights.
9 - No pride. No greed. No selfishness. Everyone would care about and for one another. No governement regulation needed. All done out of Christian goodwill.
10. No revenge, Forgiveness instead.
11. No racism.
12. No oppresion of human rights. Free speech. Freedom to worship.
13. The right to bare arms would be moot. No need to have a gun for protection, except from wild animals. No complaints about who can or should own a gun. All would be for hunting or sport. No need to arm yourself for protection.
14. No jails or prisons.
15. No broken homes and none of the negaitve fallout.
16. There's a lot more, but I don't want to keep writing.
