The Word of God Is Spiritual Food

“Jesus answered, It is written....Man does not live on bread alone, but on every word that comes from the mouth of God” (Matthew 4:4)

The Lord uses the sword of the Spirit in his reply. The word quoted, found in Deu 8:3, should be used in its connection, in order to comprehend its force. He - suffered thee to hunger, and fed thee - God never permits any tribulation to befall his followers, which he does not design to turn to their advantage. When he permits us to hunger, it is that his mercy may be the more observable in providing us with the necessaries of life. Privations, in the way of providence, are the forerunners of mercy and goodness abundant.

But by every word, etc. The meaning is: If it pleases God to sustain by other means than bread, it will be done. His word can be trusted. God fed Israel with manna, sent by his word, and we can trust his promises.

It Causes Spiritual Growth

“Brothers, I could not address you as spiritual but as worldly – mere infants in Christ.  I gave you milk not solid food, for you were not ready for it...” (1 Cor 3:1,2).

“Like newborn babies, crave pure spiritual milk so that by it you may grow up in your salvation (1 Pet 2:2).

 
God’s aim for each of us is expressed in Ephesians 4:12-15: “....that the body of Christ may be built up until we all reach unity in the faith and in the knowledge of the Son of God and become mature, attaining to the whole measure of the fullness

His Word Is The Light Of Our Lives.

“And we have the word of the prophets made more certain and you will do well to pay attention to it, as to a light shining in a dark place, until the day dawns and the morning star rises in your hearts.” (2 Peter 1:19)

As unto a light that shineth in a dark place - That is, the prophecies resemble a candle, lamp, or torch, in a dark room, or in an obscure road at night. They make objects distinct which were before unseen; they enable us to behold many things which would be otherwise invisible. The object of the apostle in this representation seems to have been, to state that the prophecies do not give a perfect light, or that they do not remove all obscurity, but that they shed some light on objects which would otherwise be entirely dark, and that the light which they furnished was so valuable that we ought by all means to endeavor to avail ourselves of it. Until the day shall dawn, and we shall see objects by the clear light of the sun, they are to be our guide. A lamp is of great value in a dark night, though it may not disclose objects so clearly as the light of the sun. But it may be a safe and sure guide; and a man who has to travel in dark and dangerous places, does well to "take heed" to his lamp.

Until the day dawn - Until you have the clearer light which shall result from the dawning of the day. The reference here is to the morning light as compared with a lamp; and the meaning is, that we should attend to the light furnished by the prophecies until the truth shall be rendered more distinct by the events as they shall actually be disclosed - until the brighter light which shall be shed on all things by the glory of the second advent of the Saviour, and the clearing up of what is now obscure in the splendors of the heavenly world. The point of comparison is between the necessary obscurity of prophecy, and the clearness of events when they actually occur - a difference like that which is observable in the objects around us when seen by the shining of the lamp and by the light of the sun. The apostle directs the mind onward to a period when all shall be clear - to that glorious time when the Saviour shall return to receive his people to himself in that heaven where all shall be light. Compare Revelation 21:23-25; Revelation 22:5. Meantime we should avail ourselves of all the light which we have, and should apply ourselves diligently to the study of the prophecies of the Old Testament which are still unfulfilled, and of those in the New Testament which direct the mind onward to brighter and more glorious scenes than this world has yet witnessed. In our darkness they are a cheering lamp to guide our feet, till that illustrious day shall dawn. Compare the notes at 1 Corinthians 13:9-10.

And the day-star - The morning star - the bright star that at certain periods of the year leads on the day, and which is a pledge that the morning is about to dawn. Compare Revelation 2:28; Revelation 22:16.

Arise in your hearts - on your hearts; that is, sheds its beams on your hearts. Until you see the indications of that approaching day in which all is light. The period referred to here by the approaching day that is to diffuse this light, is when the Saviour shall return in the full revelation of his glory - the splendor of his kingdom. Then all will be clear. Until that time, we should search the prophetic records, and strengthen our faith, and comfort our hearts, by the predictions of the future glory of his reign. Whether this refers, as some suppose, to his reign on earth, either personally or by the principles of his religion universally prevailing, or, as others suppose, to the brighter revelations of heaven when he shall come to receive his people to himself, it is equally clear that a brighter time than any that has yet occurred is to dawn on our race, and equally true that we should regard the prophecies, as we do the morning star, as the cheering harbinger of day.

“....The commands of the Lord are radiant, giving light to the eyes.” (Psalm 19:8).

“Your word is a lamp to my feet and a light for my path....The entrance of your words gives light; it gives understanding to the simple” (Psalm 119:105,130)

The Word of God is like Water

It Cleanses.

 We start life in the Kingdom of God totally “washed clean” by the Word of god.   “You are already clean because of the word I have spoken to you.” (John 15:3)

Now ye are clean - Καθαροι εστε, Ye are pruned. As our Lord has not changed the metaphor, it would be wrong to change the expression.

Through the word - Δια τον λογον, Through that word - that doctrine of holiness which I have incessantly preached unto you, and which ye have received. Perhaps our Lord more immediately refers here to the words which he had spoken concerning Judas, John 13:21-30, in consequence of which Judas went out and finished his bargain with the chief priests; he being gone off, the body of the apostles was purified; and thus he might say, Now ye are clean through the word which I have spoken unto you.

It Keeps Clean.

The Word of God, planted in our hearts, keeps us from sin.  “How can a young man keep his way pure? By living according to your word......I have hidden your word in my heart that I might not sin against you (Psalm 119:9.11)

Thy word have I hid in mine heart,.... Not only heard and read it, but received it into his affections; mixed it with faith, laid it up in his mind and memory for future use; preserved it in his heart as a choice treasure, where it might dwell richly, and be of service to him on many occasions; and particularly be of the following use:

that I might not sin against thee; the word of God is a most powerful antidote against sin, when it has a place in the heart; not only the precepts of it forbid sin, but the promises of it influence and engage to purity of heart and life, and to the perfecting of holiness in the fear of the Lord; and all the doctrines of grace in it effectually teach the saints to deny all sin and worldly lusts, and to live a holy life and conversation; see 2 Corinthians 7:1.
