Here’s a version of the Beatitudes (Matthew 5: 1-12) suitable for use with children. It was written by Carolyn Brown on her excellent Worshipping with Children website.
The Beatitudes: An Intergenerational Version
(based on Matthew 5: 1-12)
Blessed are the saints who trust God’s power and loving care,
for they are part of the kingdom of heaven.
Blessed are the saints when they are sad because the world is so unfair,
They have God’s promise that justice will come.
Blessed are the nobodies who know they are nobodies and still do God’s work.
In God’s world they are the leaders.
Blessed are the saints whose greatest wish is to do what God desires.
God will give them what they want.
Blessed are the saints who treat other people gently,
God will treat them gently.
Blessed are the saints who get in trouble when they do what God requires,
For they are surely among God’s saints.
