The Maharal (in Gur Aryeh in the beginning of Bereishis) says, "Our avodas Hashem through Torah and Tefillah that's how we bring forth the kavod Hashem." That's the purpose of creation is to increase honor heaven.
Avodah is reference to Torah and Tefillah. We serve Hashem through davening. What greater honor can we show Hashem, then the fact that we are his servants? Our lives are dedicated totally in the service of Hashem. If that's where the honor of Hashem comes from, then if we G-d forbid, are מזלזל in our Tefillos, avdus and honoring Hashem, r"l פרניעות.
Does anyone know where the Maharal in Bereishis say this?
