Launch Out

A ship is built on land but is made for the sea--
Land is safe, solid; no fears of uncertainties.
The sea is untamable--no garauntees.

All my life I've been built on solid ground;
Now Your Spirit calls me into deep waters.
Part of me yearns for it and dreads it at the same time.

Is there anything as ridiculous as a ship that stays on land?
Shame me until I launch out and face the sea I was created for!
