Here’s another prayer in the collection of National Prayers on this website. This one comes from the United Church of Christ in Medfield.
Lord God Almighty,
you have made all the peoples of the earth for your glory,
to serve you in freedom and in peace:
Give to the people of our country
a zeal for justice and the strength of forbearance,
that we may use our liberty in accordance with your gracious will;
through Jesus Christ our Lord,
who lives and reigns with you and the Holy Spirit,
one God, for ever and ever. Amen.
