Is It Biblical in asking Blessed Mary, Angels, and Saints to PRAY FOR US ?

Dear One's You will find in Scripture
"The Angels and Saints " Do know what is
going on in our world. We know" Blessed Mary "is
Jesus Mother,"Holy Mother of God" and We can
ask her to pray for Us. 
We can and should ask other's to pray for us
here on earth, however
"The Heavenly Court" as mentioned above are
already in the face of Jesus, and in His Glory !

PSALM 103 Verses 20-21: 
 We pray : Bless the Lord, O you his Angels,
you mighty ones, who do His Word,
Hearkening to the Voice of His Lord !
Bless the Lord, all his host,
his ministers that do His will

PSALM 148 Verses 1-2: 
"Praise the Lord !
Praise the Lord from the
Heavens, Praise Him
in the heights !
Praise Him, all his Angels,
Praise Him all his Host !

Not Only Do Those In Heaven Pray With Us,
They Also Pray For Us. 
REVELATION Ch . 5 Verse 8
John sees that " the twenty-four
elders (leaders of the people of God
in Heaven.) fell down before
the lamb, each holding a harp,
and with golden bowls
fell of incense, which are
the prayers of the saints.
Thus, the saints in heaven
offer to God the prayers, of
the saints on earth.
The Angels do the same thing;
REVELATION Ch. 8 Verses 3-4
"An Angel came and stood
at the altar (in Heaven)
with a golden censer and
he was given much incense
to mingle with the prayers
of all the saints upon the
golden altar before the throne,
and the smoke of the incense
rose with the prayers of the
Saints from the hand of the
Angel before God."

MATTHEW Ch. 18 Verse 10
Jesus himself warned us not to mess
with small children because their guardian
Angels have guaranteed intercessory
access to the Father. "See that you
do not despise one of these little
ones for I tell you that in Heaven
their Angels always see the face
of my Father who is in Heaven.

1 TIMOTHY Ch. 2 Verse 5
Because he is the only God-man
and the mediator of the New Covenant,
Jesus is the only mediator between
man and God.
but this in no way means we
cannot or should not ask our
fellow Christians to pray
with us, and for us.
1 TIMOTHY Ch. 2 Verse 1-4
In Particular, we should ask
the intercession of those
Christians in heaven,
who have already had their
sanctification completed,
for "The prayer of a 
righteous man has great power
in its effects ; James Ch 5 Verse 16 or
The fervent petition of a holy man
is powerful indeed. )
Those whom are already in Heaven
in God's Glory are Holy !
We are not offending Our Lord, in
anyway in asking for the 
Heavenly Court to 
PRAY FOR US !!
