What American Christians Were Reminded of on 9/11

What a previous generation of American Christians were reminded of on December 7, 1941, another generation was reminded of on September 11, 2001.  May these words from Psalm 46 bring renewed comfort and hope to us on this anniversary of that day:

God is our refuge and strength,
a very present help in trouble.
Therefore we will not fear
though the earth gives way,
though the mountains be moved
into the heart of the sea,
though its waters roar and foam,
though the mountains tremble at its swelling.
There is a river whose streams make glad
the city of God,
the holy habitation of the Most High.
God is in the midst of her;
she shall not be moved;
God will help her when morning dawns.
The nations rage, the kingdoms totter;
he utters his voice, the earth melts.
The LORD of hosts is with us;
the God of Jacob is our fortress.

--Psalm 46:1-7
