Sorry I know that "kanpeki ja nai" is "it's not perfect" but I'm not sure about the last sentence ! Kimi /anata wa kanpeki na hito janai = you're not a perfect person. Watashitachiwa kanpeki na hito janai =we aren't perfect. Kamisama wa kanpeki na = God is perfect ! Ja ne !

There is no perfect 　完璧な人間などいない 　　kanpeki na ningen nado inai i'am not perfect 　私は完璧ではない 　　watashi wa kanpeki dewa nai you are not perfect 　あなたは完璧ではない 　　anata wa kanpeki dewa nai we are not perfect 　私達は完璧ではない 　　watashitachi wa kanpeki dewa nai god is perfect 　神は完璧である 　　kami wa kanpeki de aru
