One of the chassidishe rebbes once told a chassid who had mentioned to him that he is not a baal teshuva (meaning, he’s FFB) “Un Farvos Takeh Nisht???” (And, takeh, why not???)
The lesson is-that regardless of our upbringing in terms of observance, we must constantly be improving and perfecting our ruchniyus. We must all be Baalei Teshuvah on our own level.
