And we can see that John in his Prologue parallels the Genesis 1 account of Creation once again pointing to the Son. All Scripture point to Him. Its all about Him from cover to cover.
Jesus declared the OT was about Himself
Luke 24:25-27
25 And He said to them, "O foolish men and slow of heart to believe in all that the prophets have spoken! 26 " Was it not necessary for the Christ to suffer these things and to enter into His glory?" 27 Then beginning with Moses and with all the prophets, He explained to them the things concerning Himself in all the Scriptures.
John 5:39-40
39 "You search the Scriptures because you think that in them you have eternal life; it is these that testify about Me; 40 and you are unwilling to come to Me so that you may have life.
Luke 24:44-45
44Now He said to them, "These are My words which I spoke to you while I was still with you, that all things which are written about Me in the Law of Moses and the Prophets and the Psalms must be fulfilled." 45 Then He opened their minds to understand the Scriptures,
Jesus said the Holy Spirit will bear witness of HIM
John 15:26
“When the Advocate comes, whom I will send to you from the Father—the Spirit of truth who goes out from the Father—he will testify about me. 27 And you also must testify, for you have been with me from the beginning.
John 16:7-9
But very truly I tell you, it is for your good that I am going away. Unless I go away, the Advocate will not come to you; but if I go, I will send him to you. 8 When he comes, he will prove the world to be in the wrong about sin and righteousness and judgment: 9 about sin, because people do not believe in me
John 16:13-14
But when he, the Spirit of truth, comes, he will guide you into all the truth. He will not speak on his own; he will speak only what he hears, and he will tell you what is yet to come. 14 He will glorify me because it is from me that he will receive what he will make known to you.
So I always bear witness to the Son who is God, Creator, Redeemer, Savior, Lord, YHWH, Alpha and Omega, the First and the Last, The King of Kings, the Lord of Lords, the Lord God Almighty, The True God and Eternal life. The Only Sovereign and Lord, the One Lord, God in the flesh, etc...........
hope this helps !!!
