Effort is very necessary for all good things

 Pele Yoetz (hishstadlus). Effort is very necessary for all good things whether mundane worldly matters or spiritual matters - even though everything is from G-d. In fact G-d has decreed that according to effort exerted will be the success. This is especially true regarding the great effort needed to be done in order to save the lives of those condemned to death. Many times we have seen or heard about cases where someone could have been saved easily but because of inaction and unwillingness to spend money and the price was raised considerably to possibly save the person from a horrible and painful death and sometimes the opportunity was lost. Therefore, everyone is obligated, especially the rich and famous, to quickly rescue all those that they can at the earliest possibility. It is widely known that the saving of life is a great mitzvah for which the observing of the Torah is displaced and a sefer Torah can be sold and clearly a person is obligated even to spend all his wealth. Our Sages say Saving a single Jew is equivalent to saving the entire world.
