A prayer before preaching (based on Isaiah 55:8-12). A sermon based on this text can be found at like rain and snow.
You whose thoughts are not our thoughts,
You whose ways are not our ways,
as You send forth the rain and the snow
to water the earth
giving seed to the sower
and bread to the eater ...
even so, now speak your Word of life.
Do not let it return to You empty
but let it accomplish Your purposes
and succeed in the thing for which You send it.
That we may yet go out in joy
and be led forth in peace
by the crucified and risen One
in whom Your purposes are revealed
and Your success is accomplished.
