(KJV.) ST. MATTHEW 4:4
(4) But he answered and said; It is written: Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God.
IT IS WRITTEN!
In the beginning of creation was the Word, (Jesus Christ) and Word was with God, the Almighty creator, and the Word was God himself; read St. John 1-5: let us analyze this most important verse of creation together.
Note this carefully, in the beginning of creation the Word was already there and was with God, by him, (the word) and through him, (Jesus Christ) all the things of heaven and earth were created, without him, nothing was created, that was created; so, let us appreciate the Word, which came in the flesh as Jesus Christ our Lord and Savior.
Comprehensibly; the words that comes out of the mouth of God, has power to create whatever he thinks about, sustain lives upon the earth without physical nutrients, for, Moses was with God on the mount Sinai, for forty days and forty nights, without eating bread nor drink water, cf. Exodus 34:28, regardless, he survived in his holy presence; therefore, as children of the Most High God, he can sustain our lives, at anywhere, under any type of pressure without food or water, if we obey his words, and walk in his righteousness.
Jesus Christ, was led up of Spirit into the wilderness to be tempted by the devil, after he fasted for forty days and forty nights, and was hungry, the devil said to him; "If thou be the Son of God, command that these stones be made bread."; Jesus replied, "Man shall not live by bread alone, but by every word that comes out of the mouth of God." Jesus Christ overcame the devil's temptations by his quotations from the scriptures: read through St. Matthew chapter 4 verses 4 to 11, for further clarifications.
Consequently, the Word is the sword of the Spirit, cf. Ephesian 6:17; let us read the scriptures carefully, daily to absorb its teachings, gain wisdom and spiritual strength to counteract the attacks of the enemy; also, if God has spoken to you about anything? Believe it, that whatever he said to you, is already in existence, at the moment he said it to you, it is yours, to keep forever; for, he cannot lie to you, or eat up his own spoken words. At the appointed time, the word, (Jesus) will make himself clear to you. Amen and Amen!
Grace and Peace be unto you!
(KJV.) Proverbs 8:8-9; All the words of my mouth are in righteouness; there is nothing froward or perverse in them. They are all plain to him that understandeth, and right to them that find knowledge.
