Are we allowed to risk our lives and hoping for G - d's Help ?

B"H

Jewish law forbids us putting ourselves in unnecessary danger and then asking for G - d's help saving us from any damage. Bungee jumping or climbing the highest mountains for fun and reputation, for instance.

The Talmud Tractate Shabbat 32a teaches us a statement of Rabbi Yannai:

"Let a person never stand in a dangerous place, saying to himself that G – d will perform a miracle for him and save him from harm – for perhaps He will not perform a miracle for him. And even if G – d does perform a miracle for the person, He will deduct it from his merits; the miracle does not come without his paying a price".
