Yahweh's Word is Truth. His Word reveals things as they truly are. He presents His attributes, purposes and rules (Commands) that are to be followed, as well as giving us insight into mortal Mankind's true state of affairs. The Truth Yahweh shares gives us insight into what is required of a person to be deemed worthy of the Ransom Sacrifice, and what it takes to be sanctified (made holy in His eyes), which also sets apart those he chooses for use in His service in this spiritual war; and reveals what one must do in order to remain in a sanctified state. That's why Jesus Christ prayed concerning his Chosen Ones: John 17:17 "Sanctify them by the truth; Your word is truth." The ones Chosen were Set apart for special use. They, like Jesus, would become examples for people that followed in Christ's footsteps.
The Message of TRUTH became known as "The Gospel." You've heard the expression, "It's the Gospel Truth." That is where it originally came from:
James 1:18 "By His own choice, He gave us a new birth by the message of truth so that we would be the firstfruits of His creatures."
So what is the Truth? It is the Gospel of the Word. All things inspired by Yahweh therein, are the Truth. What is the Gospel? It is the WORD. Who is the Word? Jesus Christ; therefore, Jesus Christ is the Truth, because the Gospel therein rests upon Christ.
John 1:14 "The Word became flesh and took up residence among us. We observed His glory, the glory as the One and Only Son from the Father, full of grace and truth."
Ephesians 4:19-23 "They became callous and gave themselves over to promiscuity for the practice of every kind of impurity with a desire for more and more. But that is not how you learned about the Messiah, assuming you heard Him and were taught by Him, because the truth is in Jesus: you took off your former way of life, the old man that is corrupted by deceitful desires; you are being renewed in the spirit of your minds; you put on the new man, the one created according to God's [likeness] in righteousness and purity of the truth." In part, it said: "because the truth is in Jesus" because Christ is the TRUTH and the Word of Yahweh.
John 14:17 "He is the Spirit of truth. The world is unable to receive Him because it doesn't see Him or know Him. But you do know Him, because He remains with you and will be in you." Yahweh "is the Spirit of truth."
Jesus spoke to his disciples saying: John 16:12-13 "I still have many things to tell you, but you can't bear them now. When the Spirit of truth comes, He will guide you into all the truth. For He will not speak on His own, but He will speak whatever He hears. He will also declare to you what is to come. He will glorify Me, because He will take from what is Mine and declare it to you."
The Comforter ("Spirit of truth") that he was speaking of at that time that would soon come to them, was Yahweh's Active Force. When Jesus said, "For He will not speak on His own" he was referring to the fact that the Active Force always works in conjunction with Yahweh's Will, for the Active Force is an extension of Yahweh's power. "For He will not speak on His own, but He will speak whatever He hears." He was revealing that his Father's Active Force is always in union with Yahweh. When we think of an extension of our bodies, we think of legs, arms, fingers, toes, etc. But Yahweh is a spirit, and his Active Force is alive, and can be in many places at one time.
Matthew 18:20 "For where two or three are gathered together in My name, I am there among them."
He was speaking of the Active Force that bonds Christ's followers to him.
John 14:26 "But the Counselor, the Holy Spirit; the Father will send Him in My name; will teach you all things and remind you of everything I have told you."
The Counselor, The Comforter, the Holy Spirit, it is Yahweh's Active Force. Those are simply other names used to describe it.
Hebrews 1:13 "Now to which of the angels has He ever said: Sit at My right hand until I make Your enemies Your footstool? Are they not all ministering spirits sent out to serve those who are going to inherit salvation?"
Speaking of Christ being Chosen as the King over the Kingdom Yahweh has given him. And speaking of the Holy Angels that serve in the spiritual war that are helping those mortals that serve Yahweh and Christ.
Joshua 24:14 "Therefore, fear the LORD and worship Him in sincerity and truth. Get rid of the gods your ancestors worshiped beyond the Euphrates River and in Egypt, and worship the LORD."
Yahweh wants to be worshiped in Truth and with sincere feelings from your heart that he is a Just and righteous God. He says "fear the Lord," because that is the beginning of learning the Truth about Him.
Proverbs 1:7 "The fear of the LORD is the beginning of knowledge; fools despise wisdom and instruction."
Keep His Commands; They are His Rules:
Psalms 119:60 "I hurried, not hesitating to keep Your commands."
So what is the Gospel of the Word?
Psalms 119:160 "The entirety of Your word is truth, and all Your righteous judgments endure forever."
The Gospel is the Truth found within the entirety of the Word.
