Kitzur Tefilat Amecha #42-43

[adapted by Rabbi Shmuel Jablon from Rav Aviner's three-volume commentary on the siddur "Tefilat Amecha"]

#42
In the second paragraph of Shema, we accept that Hashem has given us the Mitzvot and that we will follow them. As part of this, we read that we are “to love Hashem Your G-d and serve Him with all your hearts and all your souls.” This is very important. Our motivation to fulfill the Mitzvot is our love of Hashem. Although one can perform Mitzvot without love or desire, this is far less than ideal. Doing the Mitzvot with joy is part of the Mitzvot themselves. To perform Mitzvot without love and joy and only out of obligation is like a husband telling his wife, “I don’t really love you. I’m just with you because I promised.” Thus, we are told in the Shema that loving Hashem is part and parcel of the Mitzvot that we deserve.

In the second paragraph of Shema, we accept that Hashem has given us the Mitzvot and that we will follow them. As part of this, we learn the principle of reward and punishment. If the Jewish People perform the Mitzvot, we are rewarded. If not, we are punished.
It is important to note that the punishment includes lack of rain and crops, and that we will be sent out of Eretz Yisrael. We see that living outside of Eretz Yisrael is neither ideal nor enjoyable. It is a punishment. This is because while it is true we can serve Hashem outside of Eretz Yisrael, we can only do so as individuals. The only way to serve Hashem as a Nation is in Eretz Yisrael. This is why Hashem told Avraham Avinu to go to Eretz Yisrael where He would make him into a Great Nation - not just a great person. Therefore, the greatest punishment is to be sent away from the good land that Hashem has given us.
