Prayers of Judaism in The 2nd Beis haMikdosh (Temple) period were composed of
7 requests. It also had to have 3 sections and this was the specific
structure.
The prayer always began with The SHEVA (Praise to HASHEM=G-d),
Then followed by the TEFILAH (one's own personal pleas)
& concluded by the HODAYAH, which concludes the prayer by giving
thanks.
Example ...
The SHEVA
1.Our Father in heaven, hallowed be your Name.
2.Your Kingdom come
3. Your will be done on earth as it is in in the world to come.
TEFILAH
4. Give us this day our daily bread.
5.and forgive us our debts as we also have forgiven our
debtors.
6.And lead us not into temptation but deliver us from the yetzer hora.
[the evil inclination, or.. the evil one],
HODAYAH
7.for your's is the Kingdom , and the power , and the glory
forever...Omeyn!
Now, lets look at the context matter in Mourners' Kaddish which is
so similar to Moshiach's Tefilah. We say this prayer during the three times a day that we daven (pray), this is done in a minyan (group of 10 or more men)...yes, that is 10, not "two or more", but "ten" (or more) men.
Yisgadol v'sikadash sh'may rabo
May his name be exalted & sanctified
B'olmo di v'ro chir-usayh.
in the world that He created as HE willed.
V'yamlich Malchu'say.
May HE give will to HIS kinship
b'cha-yaychin uvyomaychon
in your lifetime & in your days
uvcha-yay d'chol bays Yisro-yel
and in the lifetime of the entire Family of Yisroel
ba-agolo u-vizman koriv.
swiftly and soon.

The structure of these two important prayers of Judaism are
important to apply to our lives, let us petition HASHEM (G_d) to fill us
with his Ruach haKoidesh (Holy Spirit) so we may take part in fufilling
his will...for this world, & for the world to come!
