Here’s a prayer of confession for Palm/Passion Sunday from John Paarlberg. It was posted on the Reformed Church in America website.
Palm Sunday Prayer of Confession
entered the rebellious city that later rejected you:
we confess that our wills are as rebellious as Jerusalem's,
our faith is often more show than substance,
our hearts are in need of cleansing.
Have mercy on us, Son of David, Savior of our lives.
Help us to lay at your feet all that we have and all that we are,
trusting you to forgive what is sinful,
to heal what is broken,
to welcome our praises
and to receive us as your own.
