"I need to feel whole"

I so valued this prayer this morning. It is from Kenneth G. Pfifer's "A book of uncommon prayer", quoted in "A guide to prayer for all God's people" (Upper Room Books). The prayer is called  "I need to feel whole". Here it is:

O God, what is Spirit?
How do I worship in spirit and in truth?
I am a solid, earthly creature,
my feet planted firmly on the ground,
my life based upon material things.
I like to touch and feel before I believe.
I am accustomed to dealing with houses, land and money, with bread, meat, and potatoes,
with objects handled, weighed, and valued
by my own standards.
I am uncomfortable with what cannot be analysed
or dissected or given market value.
What is Spirit?
Yet, O Lord, the very things I handle and see
lose meaning when they become ends in themselves.
They are all given meaning by the things of the spirit,
by love and hope and faith.
I know when I come down to it,
if I have all kinds of earthly goods
and have not love,
I have nothing.
I need the mystery beyond the tangible.
I need the things of the spirit
to give meaning to the material things I prize.
I cannot divide life up,
you have made it whole.
If I avoid love, diminish hope, deny faith,
my appreciation of my house and land,
my meat and potatoes, shrinks.
And I become a little man
with little aims and little power.
So help me to see that I worship in spirit and in truth,
not just through the use of right words
in the right place at the right time.
I worship in spirit and in truth
as life assumes wholeness.
I worship in spirit
as life takes on shape and form,
and I glory in it all.
I worship in truth insofar as I know that
no life can be separated from your Spirit.
I worship as I offer it all unto you. Amen.
