"Man shall not live by bread alone, but by every word that comes from the mouth of God."
This means that our aim is to live by the Word of God. The bible should shape and form everything we do. Life's instructions come from here. Without God's Word, we have nothing. If we don't know God's Word, then we are nothing.
So, we must be students of the bible.
We need to read it, learn its teachings, let it marinate in our souls, act upon what we learn, fellowship around it and ultimately, spread its good news throughout the earth.
In 1 Peter 2:2, God commands us to have intense yearnings, longings,
and cravings for Scripture, as a newborn infant craves milk.
