Man does not live on bread or physical food alone. But rather man lives on the Word of God – spiritual food that has a God-life-force. This Word is Jesus; the Son of God.
Deuteronomy 8:1 You must carefully keep all the commandments that I am commanding you today, so that you may live, and multiply, and go in and possess the land which the Lord swore to your fathers. 2 You must remember that the Lord your God led you all the way these forty years in the wilderness, to humble you, and to prove you, to know what was in your heart, whether you keep His commandments or not. 3 He humbled you and let you suffer hunger, and fed you with manna, which you did not know, nor did your fathers know, that He might make you know that man does not live by bread alone; but man lives by every word that proceeds out of the mouth of the Lord.
Matthew 4:4 But He answered, It is written, Man shall not live by bread alone, but by every word that proceeds out of the mouth of God.
Luke 4:4 Jesus answered him, It is written, “Man shall not live by bread alone, but by every Word of God.”
John 1:1 In the beginning was the Word, and the Word was with God, and the Word was God. 2 He was in the beginning with God. 3 All things were created through Him, and without Him nothing was created that was created. 4 In Him was life, and the life was the Light of mankind. 5 The Light shines in darkness, but the darkness has not overcome it. … 9 The true Light, which enlightens everyone, was coming into the world. 10 He was in the world, and the world was created through Him, yet the world did not know Him. 11 He came to His own, and His own people did not receive Him. 12 Yet to all who received Him, He gave the power to become sons of God to those who believed in His Name, 13 who were born not of blood, nor of the will of the flesh, nor of the will of man, but of God.
John 5:26 For as the Father has life in Himself, so He has given to the Son to have life in Himself, and has given Him authority to execute judgment also, because He is the Son of Man.
Isaiah 55:3 Incline your ear, and come to Me. Listen, so that your soul may live, and I will make an everlasting covenant with you, even the sure mercies of David.
All things in the earth and in the heavens were created through Jesus the Word. And without the Word of God nothing was created. In the Word is life and light. World does not recognize Jesus. But those who recognize and receive Him, He gaves the power to become the sons (and daughters) of God. We have Jesus’ authority to execute what we hear from the Lord God. We are to listen so that we may live in the eternal life and light of the world.
