Prayer for mercy and help

Isaiah 64:3-12

When you did awesome things which
   we did not expect,
You came down, the mountains
   quaked at Your presence.
For from days of old they have no
   heard or perceived by ear,
Nor has the eye seen a God besides
   You,
Who acts in behalf of the one who
   waits for Him.
You meet him who rejoices in doing
   righteousness,
Who remembers You in Your ways.
Behold, You were angry, for we
   sinned,
We continued in them a long time;
And shall we be saved?
For all of us have become like one
   who is unclean,
And all our righteous deeds are like a
   filthy garment;
And all of us wither like a leaf,
And our iniquities, like the wind,
   take us away.
There is no one who calls upon Your
   name,
Who arouses himself to take hold of
   You;
For You have hidden Your face from
   us
And have delivered us into the power
   of our iniquities.

But now, O Lord, Your are our
   Father,
We are the clay, and you are the potter;
And all of us are the work of Your
   hand.
Do not be angry beyond measure,
   O Lord,
Nor remember iniquity forever;
Behold,look now, all of us are your
   people.
Your holy cities have become a
   wilderness,
Zion has become a wilderness,
Jerusalem a desolation.
Our holy and beautiful house,
Where our fathers praised You,
Has been burned by fire;
And all our precious things have
   have become a ruin.
Will You restrain Yourself at these
   things, O Lord?
Will You keep silent and afflict us
   beyond measure?
