1. What does it mean that we are going to be ממליך Hashem? If Hashem is already a Melech (as we know He is, as we call Him Melech all throughout davening), how are we being ממליך One Who is already a "sitting" King?
I was prompted to the question in Birchos Krias Shema where we say, וּמַמְלִיכִים, even though Hashem is already the King as we know.
Same question I have in Birchos Krias Shema, להקדיש ליוצרם, if Hashem is already Kadosh, how are they being מקדיש an already Kadosh?
2a. In benching we say, הַמֶּלֶךְ הַטּוֹב וְהַמֵּיטִיב לַכֹּל, שֶׁבְּכָל יוֹם וָיוֹם הוּא הֵיטִיב, הוּא מֵיטִיב, הוּא יֵיטִיב לָנוּ, הוּא גְמָלָנוּ, הוּא גוֹמְלֵנוּ, הוּא יִגְמְלֵנוּ לָעַד. Is לָעַד connected only to הוּא גְמָלָנוּ, הוּא גוֹמְלֵנוּ, הוּא יִגְמְלֵנוּ or to the whole clause starting from הַמֶּלֶךְ הַטּוֹב וְהַמֵּיטִיב לַכֹּל, and from the fact that Hashem does this ongoing chesed (לָעַד) in both hatava and gemul, that is testament to Him being a Melech HaTov V'HaMeitiv?
2b. Furthermore, is the המשך of לְחֵן וּלְחֶסֶד וּלְרַחֲמִים וּלְרֶוַח הַצָּלָה וְהַצְלָחָה, בְּרָכָה וִישׁוּעָה, נֶחָמָה פַּרְנָסָה וְכַלְכָּלָה וְרַחֲמִים וְחַיִּים וְשָׁלוֹם, וְכָל טוֹב also a bakasha going back on both הוּא הֵיטִיב, הוּא מֵיטִיב הוּא יֵיטִיב לָנוּ, הוּא גְמָלָנוּ, הוּא גוֹמְלֵנוּ, הוּא יִגְמְלֵנוּ or only on the latter?
3. In Birchas Krias Shema,
וּמַמְלִיכִים: אֶת שֵׁם הָאֵל הַמֶּֽלֶךְ הַגָּדוֹל הַגִּבּוֹר וְהַנּוֹרָא קָדוֹשׁ הוּא
Are הַגָּדוֹל הַגִּבּוֹר וְהַנּוֹרָא adjectives of הָאֵל הַמֶּֽלֶךְ? Or maybe, are הַמֶּֽלֶךְ הַגָּדוֹל הַגִּבּוֹר וְהַנּוֹרָא adjectives of הָאֵל?
Also, why do we say קָדוֹשׁ הוּא?
