I think it is not about fitting a standard. It's about having
the right perspective about your relationship with God and with the
people around you. To be sinless, is to have a right relationship
with God.
The standard of sinning is so trivial tat god himself say it is
impossible. Being borned already make u sinful. Being borned is
sinful, being alive is sinful and almost anything and anytime u r
sinful. Even monks who help others in their lives r sinful. The
only solution is to believe in christ. Then they should simply
change the term to "slaves" of christ is the right relationship,
and not the word "sinless". I give an example
1) A says he like cute things
2) but everything he see is not cute, even the things tat everyone
says is cute.
3) he says blue things r cute though, even though everyone say it
is not cute
then we can conclude A like blue things, and not like cute
things
Similarly, the only right relationship is being slaves to god, and
not being sinless
If you do not believe that you are created by God, and that He
has a right to your life, then everything will be unfair and
everything God does can be considered "evil".
If I believe god create human, and he has a right to our life, I
still find it unfair and evil and tat is wat it is all about. He
kill people just because they cannot fit their standard and tat is
evil
