Man shall not live on bread alone but on every word that proceeds out of the mouth of God.
You've heard the expression, "food for the soul," it relates to the fuel needed to develop our spiritual growth. Like our bodies need food, our soul needs nourishment, the question is, what are we feeding it?
To eat something that satisfies our hunger, if it's good for our bodies, it nourishes us and energizes us. If it is not good for our bodies, it leaves us drained, unable to focus and function properly, and unable to effectively take on the tasks that we're responsible for on a daily basis.
Similarly, our soul relies on good nourishment to satisfy our spiritual hunger. God gave us the bible to be our spiritual food. The bible is the very breath of the living God, it brings life and vitality to us. Before we begin to take in God's living Word, we must prepare our soul properly to receive His nourishment. In John 6:63, Jesus told us, "It is the Spirit who gives life; the flesh profits nothing; the words which I have spoken to you are spirit and are life."
So often we attempt to fill our soul with spiritual junk in the form of new fads and the latest mind/body experience. Not that they cannot serve a purpose, in some cases, they remind us to unwind and relax so that we can better prepare ourselves to receive God's Word. However, a steady diet of empty calories can make us sick and unhealthy just like a steady diet of spiritual junk food can do the same. Whether we end up empty and unsatisfied after we've read or studied the bible depends on whether we consider the bible as life-giving food or not.
In the book of John, 6:35, Jesus declares, "I am the bread of life. Whoever comes to me will never go hungry, and whoever believes in me will never be thirsty." The Word of God is life and it gives life, the apostle Paul in 2 Timothy 3:16 said: "All Scripture is God-breathed."
If you have experienced reading God's Word in an unfulfilling manner, you can ask the Holy Spirit to come into your soul so that you can be properly fed and nourished. God asks you to freely accept His gift of salvation that comes from believing that Jesus died for your sins and has defeated death, until then, your experience with reading God's Word will not satisfy your soul's true hunger. Jesus is the way and the truth and the life. No one comes to the Father except through him. John 14:6
"This is the bread that came down from heaven. Your ancestors ate manna and died, but whoever feeds on this bread will live forever."
