For the bread of God is that which comes down from heaven and gives life to the world. . . .Jesus said to them, I am the bread of life. Whoever comes to me will never be hungry, and whoever believes in me will never be thirsty.
The grass withers, the flower fades; but the word of our God will stand forever. Isaiah 40:8
So shall my word be that goes out from my mouth; it shall not return to me empty, but it shall accomplish that which I purpose, and succeed in the thing for which I sent it.
Isaiah 55:11
