Pensamento Judaico sobre Isaías 1:13

If it is a good deed and he is praised for it, and he belittles the deed to the one who praised him, and he will consider in his thoughts that the deed is small and lacking in quality to be acceptable to the Creator due to his being obligated to do deeds many times more than this. And he will say to the one who praised him: "stop my brother, because compared to my sins, it is like a spark of fire (trying to extinguish) the sea, and even if it is worth something, how can I know if it is saved from the things which nullify a mitzvah (as described in Gate #5), and that the Creator will accept it from me, and will not return it to me, or throw it back into my face?, as written: "When you come to appear before Me, who requested this of you, to trample My courts?" (Yeshaya 1:12), and "You shall no longer bring vain flour-offerings, it is smoke of abomination to Me" (ibid 1:13).

It is well known, that whoever exhibits conflicting or contradictory behavior in word or deed - people do not believe in his integrity and have no confidence in his truthfulness. Likewise, if our exterior conflicts with our interior, if our heart's intent conflicts with our words, if our physical activities are not consistent with the convictions of our soul - our service to our G-d will not be whole, for He will not accept from us fraudulent service, as written "I cannot [bear] iniquity with assembly" (Isaiah 1:13), and "For I am the L-ord, Who loves justice, hates robbery in a burnt offering" (Isaiah 61:8), and "if you offer a blind [animal] for sacrifice, is it not evil? And if you offer the lame and the sick, is it not evil? Bring it now to your governor. Will he accept you, or lift up your face" (Malachi 1:8), and "Behold, to obey is better than a peace-offering; to hearken (is better) than the fat of rams" (Samuel 15:22).
