Kitzur Tefilat Amecha #21

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

In Mizmor Le-Todah we say to serve Hashem with "Simcha" and to serve Hashem with "Rinana". "Rinana" is outward joy and "Simcha" is the happiness that we feel inside. So it is really the most important. Only Hashem and I know if I am happy to serve Him. I can use outward expressions of joy to get closer to this true joy. But only Hashem knows what I truly feel. So I need to work on my love for Him so I will feel more and more joy at serving Him.
