Now I’m afraid to daven. my ches and chof sound alike, as do my ayin and aleph. and i’m sure i make many other mistakes. if every time i make a mistake, a deformed malach is created to testify against me, am i not better off not davening at all?
i think if one davens with the proper kavanah and tries his/her best to pronounce the words correctly, Hashem listens and understands. remember the story of the boy who only knew the aleph bais – but not how to read? he said the aleph bais with such kavanah – that was his way of davening – and the malachim took the letters and formed them into the right words for tefilah.
