As believers in Jesus Christ we must be clear that spiritual survival is not possible in the long term without feeding on the Word of God.
In the Scriptures we find in Deuteronomy 8: 3 King James Version (NIV):
And it afflicted you, made you hungry and supported you with manna, food that you did not know, nor did your parents know, to let you know that not only man will live on bread, but everything that comes out of the mouth of the Lord will live man .
This same biblical portion was quoted by our Lord Jesus Christ in Matthew 4: 4, when he faced Satan's temptations in the desert:
He answered and said: It is written: man will live not only from bread, but from every word that comes from the mouth of God.
The obvious message of this passage is that the soul cannot survive without the daily Word of God. The fact that a parallel is established with the manna that served as food for Israel in the desert shows that the believer must obtain a regular portion of God's Word and feed on it.
This is not a matter of legal duty, that is, determining personal salvation, but a matter of personal responsibility that decides our incorporation into the path of discipleship. However, let no one suppose that one can survive spiritually without feeding on the Word of God. In 1 Peter 2: 2 it is affirmed that the Word of God is as essential for the believer as milk for a baby. But just as it is imperative that we accept his Word for our survival, we must also recognize that God has provided him with sweetness to be a source of joy in our lives.
Psalm 19:10 Reina-Valera 1960 (NIV)
They are desirable more than gold and much more than refined gold; And sweets more than honey, and what is distilled from the honeycomb.
