a prayer for rain

O Almighty God, we beseech Thee,
that we who in our trouble put our trust in Thy mercy
may be strengthened by Thy defense against all adversity.

Grant us wholesome rain, O Lord, we beseech Thee,
and graciously pour forth showers from heaven on the parched face of the earth.
Through our Lord Jesus Christ, Thy Son, Who liveth and reigneth with Thee
in the unity of the Holy Ghost, God, world without end.

Amen.
