Here’s a Palm Sunday litany from the First Baptist church of Carollton, Georgia. They suggest using it as a call to worship. I think it would also make a good closing litany--a "commissioning" of God's people just before the closing benediction.
Palm Sunday Litany
(based on Luke 9:51, Matthew 16:24-25)
“Jesus set his face toward Jerusalem.” (Luke 9:51)
Our Lord is on a journey,
and the way leads through opposition and misunderstanding.
Jesus invites us to follow him.
This journey leads through the shadows of betrayal,
the night of Gethsemane,
the afternoon darkness of Golgotha.
“Then Jesus told his disciples,
‘If any want to become my followers,
let them deny themselves and take up their cross and follow me.
For those who want to save their life will lose it,
and those who lose their life for my sake will find it.'" (Matt. 16:24-25)
Our Lord is on a journey.
May we have the grace to follow this Christ,
and to give to him our very lives.
For in giving away our lives, we find them,
and in dying we live.
