Who is “Son of God” in the Injil or New Testament?

We find the answer in the first verses of the Gospel of John.  There the Apostle John deals with the issues of who Jesus is and lay his character out explicitly.

J. I Packer sets the stage about what John communicates here.

John knew that the phrase ‘Son of God’ was tainted with misleading associations in the minds of his readers. Jewish theology used it as a title for the expected (human) Messiah. Greek mythology told of many “sons of gods,” supermen born of a union between God and the human woman.

John wanted to make sure that when he wrote of Jesus as the Son of God he would not be understood” in those wrong ways. He wanted “to make it clear from the outset that the Sonship which Jesus claimed . . . was precisely a matter of personal deity and nothing less.

Note how John Piper interprets John 1 and gets to what John was saying about the Messiah.

To make sure of this, he did not reject the language of Father and Son. Instead, Packer says, he wrote his famous Prologue (John 1:1–18). “Nowhere in the New Testament is the nature and meaning of Jesus’s divine Sonship so clearly explained as here.”

  1. In the beginning was the Word. “Here is the Word’s eternity. He had no beginning.”
  2. And the Word was with God. “Here is the Word’s personality. The power that fulfills God’s purposes is the power of a distinct personal being, who stands in an eternal relation to God of active fellowship.”
  3. And the Word was God. “Here is the Word’s deity. Though personally distinct from the Father, he is not a creature; He is divine in himself, as the Father is.”
  4. All things were madeby him. “Here is the Word creating. . . All that was, was made through him.”
  5. And the Word became flesh. “Here is the Word incarnate. The baby in the manger at Bethlehem was none other than the eternal Word of God.”

Now after showing us who the Word is, John reveals him as “God’s Son. “We have seen his glory, glory as of the only Son from the Father” (John 1:14). “Thus John . . . has now made it clear what is meant by calling Jesus the Son of God. . .  [It is] an assertion of his distinct personal deity.” (J. I. PackerKnowing God [London: InterVarsity Press, 1973], 48–50.)

So,  we can be clear about who Jesus is.  We have the evidence that he rose from the dead.  His apostle John then defines who this man, this God-man, was and is.  It is all clearly laid out in the beginning of his Gospel.
