Isaiah 39-40: The God of All Comfort

Comfort, comfort my people, says your God.
Speak tenderly to Jerusalem, and proclaim to her
that her hard service has been completed,
that her sin has been paid for,
that she has received from the LORD's hand
double for all her sins.
A voice of one calling:
"In the desert prepare the way for the LORD
make straight in the wilderness
a highway for our God
Every valley shall be raised up,
every mountain and hill made low;
the rough ground shall become level,
the rugged places a plain.
And the glory of the LORD will be revealed,
and all mankind together will see it.
For the mouth of the LORD has spoken." - Is. 40:1-5 NIV

One day, this earth and everything upon it, all we have known, all we can comprehend, will be changed.  God will spread his presence over the earth and the mountains will crumble, the crooked will be made straight.  Everything we see now, everything we worry and fret about will be nothing more than a desert.  All tears will be wiped away. A different world will rise up and the glory of the Lord will be revealed.  For the mouth of the Lord, the God of all comfort, has spoken it.
