When Jesus comes in, there is now a kingdom of heaven that we are worthy of. And even better, all we have to do is believe in Jesus in order to get into this heaven. So now making god happy on Earth isn't important because of the free ride to eternal bliss. People now actually believe that you can get away with anything and as long as you have faith in Christ, you're in. The Christian Faith is so delusional that there no longer is anything required for ascension other than one single thought.
People are inherantly lazy.
There is a reason why the neurosis continues. Please do not misquote me. Where did Jesus say he fulfilled the law.
