כְּשֵׁם שֶׁמַּקְדִּישִׁים אוֹתוֹ בִּשְׁמֵי מָרוֹם

This morning I thought of a meaning 

for a line I've been saying my whole life:

נְקַדֵּשׁ אֶת שִׁמְךָ בָּעוֹלָם, כְּשֵׁם שֶׁמַּקְדִּישִׁים אוֹתוֹ בִּשְׁמֵי

מָרוֹם, כַּכָּתוּב עַל יַד נְבִיאֶךָ: וְקָרָא זֶה אֶל זֶה וְאָמַר

     

"May we sanctify Your name in the world 

  just like they sanctify it in the high heavens."

In heaven no-one is sanctifying G-ds name in a phony, for show, kind of way - why would they? We pray that our service on earth be done with sincerity and lack of pretension just as the angels do it in heaven.
