I've

had two hours sleep in 36 hours and I'm not really tired.

Didn't eat much either.

Isaiah 40:31 

"but those who hope in the Lord

    will renew their strength.

They will soar on wings like eagles;

    they will run and not grow weary,

    they will walk and not be faint."

Deuteronomy 8:3

"man does not live on bread alone 

but on every word that comes from the mouth of the Lord."

I love brother Joes point:

"but on every word that comes from the mouth of the Lord."

Not "came from"

Not past tense.

Every word you hear.

Pop culture references.

Secular music.

Movies.

Anywhere and everywhere.

Answers to prayers etc.

"every word that comes from the mouth of the Lord."

It will keep you going.

Promise.
