mustard seed

This can't be
you & me?
I must be blind & cannot see
God who in the world is he?
I surely do not feel the glee...
my punishment? I must pay the fee?
Get thee behind me satan!
you must flee!
my heart belongs to God
only he has the key!
every one of you must take a knee!
only the Lord can part the sea.
& i do have the mustard seed.
