We will hunger for what we feed on.

"Do not conform any longer to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God's will is—his good, pleasing and perfect will." Roms 12:2

"The Lord satisfies the longing soul, and fills the hungry with goodness." Ps 107: 9

The issue today with us is not material things, but rather that we'd allowed material things to satisfy our souls. The soul that is already satisfied is what keeps us from hearing His voice.

"Above all else, guard your heart, for it is the wellspring of life." Pro 4:23
