Each of the Jewish people is commanded to do Rama"h (248) Miswoth 'Aseh (positive commandments). Of course, it is not possible for each individual to perform all 248, because not all apply to each person.
The only way, therefore, for it to be possible, is through the love that exists between one another. In this way, each person completes his Rama"h (248) positive commandments through the actions of his fellow Jew. That is why Rama"h is made up of the same Hebrew letters as "Rahem" which is one of the interpretations of the word "love".
This hints to us that the 248 commandments will be considered performed by every single individual through the love between one another. And the performance of all 248 positive commandments helps to bring the Geullah (final redemption. From this we see how important love and caring are among the Jewish people.
