Hereās the lowdown about miracles in Judaism. Judaism does indeed believe in miracles, and certainly miracles have happened in Jewish peopleās lives in the present time, some of which may have been disguised as tragedies rather than blessings. There are several heart-warming stories about such miracles.
HOWEVER, miracles are spoken about in the Torah (for example, in Deuteronomy), and, in almost every instance, Jews are cautioned not to accept miracles as signs of G-d. In several places in the New Testament, the Apostles refer to the miracles of Jesus as irrefutable evidence of His divine origin, such as when Nicodemus witnesses the miracles of Jesus and believes in Him. The problem with this testimony is that any (educated) Pharasaic Jew of the period, such as Nicodemus, would NOT have believed in Jesus based solely on the latterās miracles. It is not a question of Jews being hard-hearted but rather of their understanding of what the Torah commands them to do and not to do. Such statements by the Apostles are in total opposition to what the Torah taught the Jews about NOT trusting miracles as evidence of the veracity of any person or religion (and miracles do appear not only in Judaism, Christianity, and Islam but in eastern religions as well). Further, the Torah tells us that G-d sometimes uses miracles as a means to test our faith. So, naturally, Jews have generally been suspicious of miracles, both of their authenticity and their significance even if true.
