Boyd’s Bible Dictionary:
The logos, or Word, in John 1:1-141In the beginning was the Word, and the Word was with God, and the Word was God. 2The same was in the beginning with God. 3All things were made by him; and without him was not any thing made that was made. 4In him was life; and the life was the light of men. 5And the light shineth in darkness; and the darkness comprehended it not. 6There was a man sent from God, whose name was John. 7The same came for a witness, to bear witness of the Light, that all men through him might believe. 8He was not that Light, but was sent to bear witness of that Light. 9That was the true Light, which lighteth every man that cometh into the world. 10He was in the world, and the world was made by him, and the world knew him not. 11He came unto his own, and his own received him not. 12But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name: 13Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God. 14And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth. (John 1:1‑14); 1 John 1:11That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life; (1 John 1:1); Revelation 19:1313And he was clothed with a vesture dipped in blood: and his name is called The Word of God. (Revelation 19:13), stands for the Son of God, the Word incarnate
Concise Bible Dictionary:
A designation of the Lord Jesus, employed by John in the opening of his gospel, and mentioned in Luke 1:22Even as they delivered them unto us, which from the beginning were eyewitnesses, and ministers of the word; (Luke 1:2). The word is λόγος, which occurs constantly in the New Testament and is translated “word, saying, speech,” and so forth. In John 1 it is “the Word who is in view,” and what is stated asserts clearly three things concerning the Person of the Lord Jesus Christ.
1. His eternal existence: “in the beginning was the Word;” “all things were made by him.”
2. His true deity: “the Word was God.”
3. His distinct personality: “the Word was with God.”
As the Word, the Lord Jesus is the substance and expression of the mind of God in regard of man; and the term covers what He was on earth for man—life, light, and love. See also Revelation 19:1313And he was clothed with a vesture dipped in blood: and his name is called The Word of God. (Revelation 19:13).
It has been said that λόγος presents “the intelligent and the intelligible.” The same Greek (translated “the word”) is used to express the scriptures and the truth preached (Acts 16:66Now when they had gone throughout Phrygia and the region of Galatia, and were forbidden of the Holy Ghost to preach the word in Asia, (Acts 16:6); Acts 17:1111These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so. (Acts 17:11); Gal. 6:66Let him that is taught in the word communicate unto him that teacheth in all good things. (Galatians 6:6); Phil. 1:1414And many of the brethren in the Lord, waxing confident by my bonds, are much more bold to speak the word without fear. (Philippians 1:14); 1 Thess. 1:66And ye became followers of us, and of the Lord, having received the word in much affliction, with joy of the Holy Ghost: (1 Thessalonians 1:6); 1 Pet. 2:2,82As newborn babes, desire the sincere milk of the word, that ye may grow thereby: (1 Peter 2:2)
8And a stone of stumbling, and a rock of offence, even to them which stumble at the word, being disobedient: whereunto also they were appointed. (1 Peter 2:8); 1 Pet. 3:11Likewise, ye wives, be in subjection to your own husbands; that, if any obey not the word, they also may without the word be won by the conversation of the wives; (1 Peter 3:1); 2 Pet. 3:77But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men. (2 Peter 3:7); 1 John 2:77Brethren, I write no new commandment unto you, but an old commandment which ye had from the beginning. The old commandment is the word which ye have heard from the beginning. (1 John 2:7); Rev. 3:88I know thy works: behold, I have set before thee an open door, and no man can shut it: for thou hast a little strength, and hast kept my word, and hast not denied my name. (Revelation 3:8)).
