King?

King is your word not mine;
Friend I am, and not very choosy,
Pagans, and prostitutes,
Publicans and sinners,
Grace is my kingdom.

King is your word, not mine;
Servant I am, no one beneath me,
Feet washer and waiter,
Serving the least,
Love is my kingdom.

King is your word, not mine;
Physician I am, all free of charge,
Touching the leper,
Expelling the demons,
Health is my kingdom.

King is your word, not mine:
A prophet I am, seeing God’s word
In mustard seed and yeast,
Wildflower and ravens,
Truth is my kingdom.
