Matthew 4:4 - Jesus answered him, “The Scriptures say, ‘It is not just bread that keeps people alive. Their lives depend on what God says.’” (“It is written, ‘Man shall not live by bread alone, but by every word that proceeds from the mouth of God.’ [Deut. 8:3]”)
This is what I'm hearing the Holy Spirit say about this verse: It would be far greater for us to be spiritually fully mature but yet physically starve to death than it would be for us to be physically sustained but spiritually dead.
We desperately need to stay immersed in His Word and let it renew our minds so we can be transformed into the perfect image of His Son (2 Corinthians 3:18, Philippians 3:20-21, Romans 8:29, Romans 12:1-5).
