Jewish women have the opportunity and the obligation to influence the spiritual state of their husbands and children, enabling them to connect their entry into a state of holiness to their departure from that state.
A woman should not worry if her husband spends an extra hour at prayer or in study; it will not cause them any material loss. Similarly, a mother does not have to be concerned that training her children to study Torah the entire day might stifle their financial future. Indeed, the opposite is true. Women must encourage their husbands and children, explaining that an increase in the observance of the Torah and its mitzvos will amplify their material prosperity. For when “you follow My statutes and keep My mitzvos... I will grant you your rain at the appropriate time.”
