i believe, It‚Äôs a lot harder to convert to Judaism than to Islam. Islam has you recite the shahada (declaration of faith in God) and I think that‚Äôs only one sentence. If you choose to 

convert to Judaism, you ask the rabbi 3x. He turns you away 3x and only after your next entreaty will he allow to start the learning process. This can take years; it depends. Judaism

 doesn‚Äôt see conversion as necessary. If you follow the seven laws of Noah, you‚Äôre a good and just human
