Luke 4:4

And Jesus answered him, saying, it is written, That man shall not live by bread alone, but by every word of God.

Today I was reading to my children where Jesus was being tempted by Satan.

Toward the end it shows that Jesus said, "Man shall not live by bread alone, but by every word of God."

That means EVERYWORD OF GOD, from Genesis to Revelation.  God's word is relevant forever.  It is always in season.  Whether it is "be fruitful and multiply", to "teaching your children as you rise up, sit down, walk and lie down", that the purpose of marriage is "Godly seed", and "Go and make disciples", His word is always appropriate.  So the next time you hear a "Christian say that God didn't create the world, the flood was a "local flood", ask them to read Luke 4:4.  Ask them if they believe what Jesus said to be true?
