This text by Lutheran hymn writer Jaroslav Vajda is a marvelous exposition of Martin Luther’s description of the meaning of the First Commandment in his Small Catechism:
“‘You shall have no other gods.’  What does this mean?
Answer:  We should fear, love, and trust in God above all things.”

Who Is the One We Love the Most

Who is the one we love the most,
the one who has our total trust?
Something or someone is our God,
whose will is willingly obeyed,
to whom we give the years we live.
Let that be you, our God, our Lord!

Count every heartbeat, every breath,
trace every step from birth to death,
track every second to its source,
each drop of blood, each blade of grass,
the rising sun, and every one.
Let that be you, our God, our Lord!

Preserve us from all other gods,
all damned, deceitful, loveless frauds.
Compare them ruthlessly to you,
the only One, eternal true
Creator of all life and love.
You are that One, our God, our Lord!

A love no other god has shown,
your Son upon a cross makes known.
How shall we worship such a God
with more than words and passing nod,
if not with whole heart, mind, and soul,
like yours for us, our God, our Lord?!

You can find a choral setting by Carl Schalk here, which the Chancel Choir of Central Presbyterian Church in St. Louis will sing on March 15, 2015.
