World Food Day is October 16, 2015. Here's a prayer suitable for that day from the Third Space website.
God, the Holy Spirit,
Prayer to the Spirit on World Food Day
You are the restless wind of love that sweeps through the world.
You blow where you will, breaking down barriers,
Stirring hearts to change, making all things possible.
Make us restless for change – even impossible change.
Come, Spirit of God,
Sweep through our world bringing great change.
May the harvest of your goodness bring justice and hope.
And, for us, transformation in our praying and living,
So all may share in the harvest of your blessings.
