Matthew 4:3 "And the tempter came and said to Him, “If You are the Son of God, command that these stones become bread.”
Analogies and illustrations can break down, but the above little story can aid us in appreciating all that the Son of God went through in coming into this world. When God in the Person of the Son came into this world, the uncreated flame of His Deity was brought into contact with the fragile DNA of a virgin girl named Mary. The Divine chemist - the Holy Spirit - miraculously joined together true humanity and true deity - with the result being the Eternal Son coming through and born as the infant Jesus. Before it would be all said and done, the humanity of Jesus of Nazareth would be bent and twisted in His mission to come and save His people while all the while ever remaining that Eternal uncreated flame of Deity with the Father and the Spirit.
The incarnate Son of God is and forever will be the most supreme living Person of beauty - the centerpiece of scripture and eternity - the God-man. The eternal Son would in His incarnation learn what it was like to be an obedient Son as the historic Jesus of Nazareth (Hebrews 2:10; 5:9).
Exploring the title "Son of God" in the three Gospels of Matthew, Mark and Luke
In the above opening verse we find the first mention of this title in the New Testament. Without a doubt the term "Son" is used of Jesus in the opening chapter of Matthew's Gospel with respect to His fulfillment of Isaiah 7:14 in Matthew 1:23 and as Mary's son according to the flesh in Matthew 1:18. As one encounters the additional words "of God" in Matthew 4:13 and many other places in the Gospels and remainder of the New Testament, there is indicated a unique relationship that the Person of the Son in His incarnation as Jesus of Nazareth had with respect to God.
What we want to do is survey key texts in the first three Gospels that use this title "Son of God" and what this title has to tell us about Jesus Christ. The first three Gospels together are called the "synoptic gospels", with the term "synoptic" meaning "seen together". Such a study can aid us in better understanding how the Person of the Son of God, eternally existing in the uncreated flame of Deity along with the Father and the Spirit, voluntarily chose to come and take unto His Person the frailty of humanity untainted by sin in the virgin-birth/conception (2 Corinthians 5:21; 1 Peter 2:22).
Peter's confession in Matthew 16 is enormously important in connecting Jesus of Nazareth to the prophetic swath of Old Testament Messianic expectation. So with Matthew we gain a sense of Jesus "Heavenly origin" and "earthly mission".
The High Priest's use of the title "Son of the Blessed One" is a euphemistic way of saying "Are you the Son of God"? The use of this title along with "Christ" and then Jesus' own use of another Divine title "Son of Man" zeroes in on the climactic revelation of Jesus Christ's heavenly origin and earthly mission - just as we saw in Matthew.
Such an announcement tells us two important truths about the "Son of God" - first, that the Son of God describes the Son as He was prior to His incarnation and second, this Eternal identity would remain with Him after His incarnation. In Luke 9:35 we see the Father announcing from Heaven: "This is my beloved Son, in whom I'm well pleased, listen to Him!"
Whenever we tie in all of the previous insights from the other two Gospels, we discover that Christ's identity as Son of God is an eternal identification as He was within the Triune Godhead, and that the revelation of Him as "Son of God" is theological shorthand for saying that He is now "God in human flesh". As the New Bible Dictionary, page 503, notes: "that the Son perfectly embodies all that is in the Father, or putting it negatively, that there is no aspect or constituient of Deity or character which the Father has and the Son lacks (2 Corinthians 4:4; Colossians 1:15; Philippians 2:6; Hebrews 1:3).
Today we explored Jesus Christ as the Son of God and the significance of that title. We discovered that the first three Gospels of the New Testament, also called the "synoptic" or "seen-together" Gospels (due to their common literary and thematic inter-dependance and presentation of Jesus) speak frequently of Jesus as the Son of God. This important title tells us about Jesus' heavenly origin as the co-equal second Person of the Trinity along with the Father and the Holy Spirit. This title "Son of God" was also used to refer to His earthly mission as the Savior and as the chosen-one or Messiah.
