Now an angel of the LORD
said to Philip,
"Rise and go
toward the south to the road
that goes down from
      Jerusalem to Gaza."
This is a desert place.
And he rose and went.

                Acts 8. 26-27

(Our response is not dependent
on knowing God's purposes in it.
God always has profound designs
in what only appears
        to be wilderness,
too deep to understand,
too many dimensions to realize.)
