Leitura de hoje na missa

As the rain and the snow come down from heaven,

and do not return there till they have watered the earth,

making it fertile and fruitful,

so that it yields seed for the sower and bread for the eater,

so is my word that goes out from my mouth:

it shall not return to me void,

but shall do my will,

achieving the end for which I sent it.

(Isaiah 55:10-11)
