“But he answered, “It is written, “‘Man shall not live by bread alone, but by every word that comes from the mouth of God are’”
(Matthew 4:4)
God’s Words are equated to bread, emblematic of God’s kind of food. Bread signifies life. Jesus addressing the tempter places the Word of God as the final Sustainer of life itself. By His declaration, He establishes what is real and necessary to every disciple.
The Word of God is the food that the believer needs. Without the promises of God, we’ll “starve” inside spiritually. We must have what God is speaking, all that “the mouth of God” wants to share with us.
Deuteronomy 8:2–3 parallels Matthew 4:1–4. When Jesus is tempted three times, He quotes exclusively from the book of Deuteronomy each time. We see Him strengthening His calling by using the truth found in the OT, He establishes His ministry using the Law of Moses.
God’s words have a profound effect on our hearts. They change us from the inside out and nothing can do that. Without his words, something dies deep inside us. We look around and realize there is no real meaning.
“I will abundantly bless her provisions;
I will satisfy her poor with bread.”
(Psalm 132:15)
