Romans 1:16 ... For I am not ashamed of the gospel of Christ:
for it is the power of God unto salvation to every one that believeth;
to the Jew first, and also to the Greek.
Isaiah 55:10-11 ... 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: 11 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.
