Five times in the New Testament our Lord Jesus Christ is called the only begotten, and five times He is called the firstborn or the first begotten. In these we may see how carefully balanced is the presentation of the truth as to His divine-human personality. He is God and man in one wondrous, adorable person, and of this these two terms referring to His sonship bear witness. Five times our Lord is called the only begotten_that is what He is in His essential deity. Five times He is called first begotten_that is what He became as a man. All I shall attempt to do is to turn you from one scripture to another, linking these together with a few comments to bring out the true deity and the true humanity of our Lord Jesus Christ.
The five instances in which the term, "only begotten," is used are all found in John’s writings, four times in the gospel and once in his first epistle. The four gospel passages I will give you first. John 1:14:"The Word was made [or literally, became; it was voluntary on His part] flesh and dwelt among us, and we beheld His glory." John is speaking for himself and his fellow apostles who had companied with the Lord during those three and a half wonderful years. "We beheld His glory, the glory as of the only begotten of the Father, full of grace and truth." The expression "only begotten" is clearly a title of deity. In the opening verse of the chapter we read, "In the beginning was the Word." When everything that ever had beginning began, the Word was. In this expression we have eternity of being. "And the Word was with God"_here we have personality. "And the Word was God"_here we have true deity. "The same was in the beginning with God"_here we have eternal sonship. "All things were made by Him and without Him was not anything made that was made"_here we have the creatorial power. And this is the one who became flesh and dwelt among us! It is the eternal Word who clothed Himself with our humanity untainted by sin, therefore absolutely holy, and so walked before men that they could see the glory of the only begotten shining through the veil of His flesh.
And here let me say that the expression, "became flesh," does not merely mean that deity was clothed with a human body. The clear, unmistakable teaching of Scripture is that our Lord had a true human spirit and a true human soul as well as a real human body. Yet He never ceased to be God. "God was in Christ reconciling the world unto Himself." He was as truly God as if He had never become man and as truly man as if He had not been God; yet He was both God and Man in one undivided and indivisible person.
In John 1:18, He says, "No man has seen God at any time." That is, no man has seen deity at any time; deity as such is necessarily invisible to created eyes. "The only begotten Son, which is in the bosom of the Father, He hath declared Him." No one ever saw the invisible God until Christ made Him manifest. Man has seen various manifestations of the glory of God, but not until Jesus came into the world did any one ever really see God. In Christ we have God fully manifest, so that one can say, "Do you want to know what God is like? He is exactly like Jesus."
Some people may say that they are not ready to meet God, but it would not be so bad to meet Christ. But, my friends, the love of Christ is the love of God, as the next passage shows us. "For God so loved the world, that He gave His only begotten Son, that whosoever believeth in Him should not perish, but have everlasting life" (John 3:16). It was the love in the heart of God that gave Christ.
Jesus did not die to enable God to love sinners. Jesus came to die because God loved sinners. Get acquainted with Christ, and when you meet God in heaven you will not have to learn Him for the first time.
Now observe this expression, "His only begotten Son." Do not connect this term with any thought of generation. It is not that Jesus is the only begotten Son in the sense of being the first son that God begot, but that He is the only begotten Son in the sense of being God’s unique Son_His Son in a different way from what anyone else will ever be.
Then observe John 3:18:"He that believeth on Him is not condemned; but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God." Salvation, freedom from condemnation, is linked for you and me with faith in the eternal Son who came into the world for our salvation. Do you trust in Him? If so, "There is … no condemnation to them that are in Christ Jesus" (Rom. 8:1). Do you still reject Him? Then you are "condemned already," and that, not merely because of the many sins you have committed, but because you have spurned the only begotten Son who became man and died upon the cross for your salvation.
Let us now look at the final passage using the term "only begotten":"In this was manifested the love of God toward us, because that God sent His only begotten Son into the world, that we might live through Him" (1 John 4:9). People like to think that God is love, and that because of this He may lightly pass over their sins; but it was the love of God that provided the atonement. Also note that Christ did not become the only begotten when He was born into the world. He was with God in the glory from all eternity. "God sent His only begotten Son." These five passages, then, have to do with the deity of Christ.
Now let us consider the five scriptures that speak of Christ as the firstborn or as the first begotten. Turn to Colossians 1. Here we have the double headship of our Lord Jesus Christ_ the headship which is His because He is Creator and that which became His when He arose from the dead, "Who [that is, the Son of God] is the image of the invisible God, the firstborn of all creation" (verse 15). The Son was just as truly the invisible God before the incarnation as the Father and the Spirit were invisible. But now Christ is the image of the invisible God, the firstborn of all creation. He has made God visible. He has, as it were, compressed deity into a body, into the humanity of a man, and thus He is able to make God known to us.
The term "firstborn" is not necessarily the one born first. It is used otherwise in Scripture. The firstborn is the heir, the preeminent one, and God has ordained "that in all things He might have the preeminence" (Col. 1:18). Abraham had two sons. Ishmael, the man after the flesh, was born first; but Isaac, the child of promise, was the firstborn. Isaac had two sons. Esau was born first, but Jacob was the firstborn. And of Jacob’s sons, we know that Reuben was the firstborn according to the natural order, but the blessing of the firstborn was conferred upon Joseph. So Christ is not the firstborn in the sense of being created first, for He was uncreated and is Himself the Creator. But He is, as man, the rightful heir of all, therefore the firstborn set over all creation, the second man, the Lord from heaven.
But what did man do with God’s firstborn? They cried, "Away with Him!" They hurried Him to a cross of shame. But what happened there? He offered Himself without spot unto God, a sacrifice for our sins. He made peace by the blood of His cross, and now, having been raised from the dead, He is Head of the Church, the firstborn from among the dead. This is what we learn in Colossians 1:18. As the resurrected Man He takes His new place as Head of the Church. Because He is Creator He is Head over all the universe. Because He loved the Church and gave Himself for it, He is Head of the Body. Always preeminent in God’s thoughts, there was a higher glory than that of Creator which was reserved for Him, but He had to reach it by death and resurrection. Oh, what glories have accrued to Christ by way of the Cross!
In Romans 8 we have our Lord again spoken of as the firstborn:"Whom He did foreknow He also did predestinate to be conformed to the image of His Son, that He might be the firstborn among many brethren" (verse 29). Here we see Him as the archetypal Man_the pattern Man to whose image all His brethren shall be conformed. Some day we shall every one be just like Him_God’s blessed firstborn_when we get our glorified bodies.
In Revelation 1:5 we have a greeting "from Jesus Christ, who is the faithful witness, and the first begotten of [or properly, the firstborn from among] the dead, and the prince of the kings of the earth." Here we have our Lord as He was in the days of His flesh, "the faithful witness," the true prophet revealing God to man, then as the resurrected priest "who ever liveth to make intercession for us." It is as the firstborn from the dead that He exercises this particular office, interceding for His saints as they still tread the desert sands, exposed to trial and temptation in this world where they are called upon to witness for Him, the earth-rejected one. By and by He will return to reign as Prince of the kings of the earth. Thus we see Him as He was, as He is, and as He will be. His resurrection attests the reality of His mission and is the pledge of His coming victory over all the powers of hell.
But the story does not end here. Rejected of men, He was accepted of God, owned as His firstborn, received up into glory, and seated on the Father’s throne, "From henceforth expecting until His enemies be made His footstool." Clearly and unequivocally the inspired Word declares that He must come back to establish here over all the earth the reign of righteousness so long predicted. When He does return, He will be hailed with glad acclaim by saints and angels as the first begotten, the Son. and heir of God who takes the kingdom because it is His by right. In amazement, men who have refused His claims and spurned His grace will then behold Him coming in clouds with power and great glory, when He shall be revealed from heaven, in flaming fire taking vengeance on them that know not God, when He shall come to be admired in all who have believed the Spirit’s testimony concerning Him. And so we read in Hebrews 1:6, "And when He bringeth the firstborn into the habitable earth again, He saith, And let all the angels of God worship Him" (literal translation). He who came once and was rejected as God’s firstborn is coming into the world again, and not only will men own that He is indeed the firstborn, the first begotten from among the dead, but all angelic intelligences will fall at His feet and worship Him.
It is written in the law, "Thou shalt worship the Lord thy God, and Him only shalt Thou serve" (Matt. 4:10). But the Father calls on all the angelic host to worship Him, His firstborn_the rightful Heir and Lord of all.
If Jesus be not God all heaven will be filled with idolators! Blessed it is to bow at His feet and cry with Thomas, "My Lord and my God!"
