do unto others what others do unto you?
So if the person cheats on you then you will also cheat on them?
If they lied to you it means its ok NOT to be honest to them?
That is what the world is doing.
but Jesus said:
31 Do to others as you would have them do to you.
32 “If you love those who love you, what credit is that to you? Even sinners love those who love them.
