For as the rain cometh
down, and the snow from heaven, and returneth not thither, but watereth the
earth, and maketh it bring forth and bud, that it may give seed to the sower,
and bread to the eater:
So shall My Word be that
goeth forth out of My mouth: it shall not return unto Me void, but it shall
accomplish that which I please, and it shall prosper in the thing whereto I
sent it.
Isa 55:10-11 KJV
