Q: Sometimes I feel as though I am being called upon by G-d to tell the world about the coming of Mashiach. How should I relate to this?
Anyone who feels that he is being called by G-d to help bring closer the coming of Mashiach must devote his life to studying the manner in which to communicate to the world the Divine truth. When Mashiach will come, this is what he will reveal. It is incumbent upon each individual to help Mashiach come by studying the Torah, especially the inner dimension of the Torah which is Kabbalah and Chassidut. This is in order to gain the proper language and means of communication so that he may convey the Divine truth to the world in the true universal language, which is the symbolism of the Kabbalah as elucidated by Chassidut.
The Ba'al Shem Tov teaches us that whatever a person is shown in his life is Divine Providence and he must learn from it. If a person is shown a rock, for example, he must study in Kabbalah and Chassidut the inner meaning of the word, "rock," of the Hebrew letters which make up the word and so forth. One should study the book, "The Hebrew Letters" (click to see the shortened internet version of the "Hebrew Letters,") and then try to permute and combine the 22 letters of the Hebrew alphabet (with their intrinsic ideas as illuminated there) into words. There are many books on Kabbalah which are like lexicons or dictionaries. They are arranged alphabetically, and explain the symbolism of each word. If a person with the proper background in Kabbalah looks up the word even, "rock" or "stone," he will be able to understand the explanation of what the symbol means. Then, with G-d's help, he will also be able to relate it to his life.
It is important to remember that if a person feels called, it means he must devote his life to others. Mashiach comes to save and enlighten the world. In order to devote one's life to others, one must have the true language, which only comes from the study of Kabbalah and Chassidut.
