Palm Sunday: Matthew 21:1-11 ESV.
21 Now when they drew near to Jerusalem and came to Bethphage, to the Mount of Olives, then Jesus sent two disciples, 2 saying to them, “Go into the village in front of you, and immediately you will find a donkey tied, and a colt with her. Untie them and bring them to me. 3 If anyone says anything to you, you shall say, ‘The Lord needs them,’ and he will send them at once.” 4 This took place to fulfill what was spoken by the prophet, saying,
5 “Say to the daughter of Zion,
‘Behold, your king is coming to you,
humble, and mounted on a donkey,
on a colt, the foal of a beast of burden.’”
6 The disciples went and did as Jesus had directed them. 7 They brought the donkey and the colt and put on them their cloaks, and he sat on them. 8 Most of the crowd spread their cloaks on the road, and others cut branches from the trees and spread them on the road. 9 And the crowds that went before him and that followed him were shouting, “Hosanna to the Son of David! Blessed is he who comes in the name of the Lord! Hosanna in the highest!” 10 And when he entered Jerusalem, the whole city was stirred up, saying, “Who is this?” 11 And the crowds said, “This is the prophet Jesus, from Nazareth of Galilee.”

Jesus my Lord,
let me strengthen my courage
by taking on the courage
of all those people who have been “centurions” for me.
Many have faced disasters
and hard times with great constancy.
The upper hand of evil never turned them against you.
They kept going.
Let me be like them, Lord.
No matter what the cross,
let me never stop declaring you
to be “truly the Son of God,
the source of my hope,
the reason why I will never quit on life.
in this I pray
amen
Almighty and everliving God, in your tender love for the human race you sent your Son our Savior Jesus Christ to take upon him our nature, and to suffer death upon the cross, giving us the example of his great humility: Mercifully grant that we may walk in the way of his suffering, and also share in his resurrection; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, for ever and ever.
in this I pray
Amen
