Special prayers are recited and fast days may even be decreed by the leaders of a Jewish community, in the event of a serious drought. It is particularly important to encourage people who are not so observant of Jewish religious practices to participate in these services, in the hope that they will be moved by the vulnerable position of the community and possibly become more religious. Indeed, the Talmud states that “Any fast day that does not include the sinners is not a fast” (Kerisus 6b)
It once happened that the sun shined bright and the heat touched everyone. It had not rained for a very long time and so water was scarce. In one village, the rabbi proclaimed a fast day. The rabbi tried to urge a non-observant person to join in the community in prayer that the life giving rains should come, but the “modern” Jewish person refused, saying: “You certainly do not think that the prayers of someone like myself will make any difference to G-d.”
The rabbi tried to impress upon him that the prayers of every person are important, and when someone who has wandered away from religious observance turns to G-d, his prayer is very dear to the Holy One, blessed be He.

“I take it from this,” the man answered the rabbi, “that you are suggesting that it is my sinfulness that has aroused the anger of Heaven and caused the drought. How can I be part of a community that accuses me of this! You and your kind are so steeped in superstition that you will never know what the real world is like. This is why I don’t believe in your traditions and mythology!””
The rabbi thought for a moment, stroked his beard and answered the young man: “I’m sorry you feel that way, I could not possibly think that you caused the drought. In fact, we know for a fact that it was people like you who once caused it to rain for forty days and forty nights consecutively.”
