There is another common issue with the keeping of Shabbos. This is that there are many people who do not inquire about and learn the laws of Shabbos and because of this they commit many accidental sins relating to Shabbos and they desecrate the Shabbos unknowingly. Examples of this are many of the Rabbinical prohibitions and the prohibition of Muktzeh (items which one may not move on Shabbos) and the biblical prohibitions of trapping, sorting and washing. Similarly regarding the heating up of foods (especially at times of celebrations or special occasions) there is a lot of leeway to err and blunder and in these laws one who has not come to actually study, inquire about and learn these laws even when he grows old will not know that there was anything wrong with what he has been doing.
The truth is that Klal Yisrael are holy people and want to keep the Shabbos. However, they do not realize the severity of the prohibitions. When they hear now how severe it is maybe each person will help his friend and say “Strengthen yourself!” to his brother and maybe we will merit to keep the Shabbos according to its laws full with Torah and good deeds and the redeemer will come to Tziyon speedily in our times; Amen. So shall it be.
