spirituality of imperfection

The spirituality of imperfection is a kind of spirituality that was made io response to christianity and the difference between the two ways of thinking is very tiny: christian religion says that you should do your best un reach perfection, the spirituality of imperfection instead assume that you could never be perfect because it is the human nature to be affected by imperfection and mistakes. I think that the second one is the one that better fits reality, but i still prefer christianity because it doesn't put any limit to a person improvement and that would make us struggle the most to make ourselves better and better, also if we know from the beginning that we'll never reach God's perfection...
