Last night's reading brought to mind something about the Man of Christ. Brief summary of the chapter i'm about to quote from, a man was born blind, Jesus restored his sight to him, so the Pharisees and Judeans questioned his testimony by saying that he hadn't really been blind since birth. They wanted to believe Jesus to be a fraud and a liar, which sometimes proves quite difficult to do.
Jesus heard that they had cast him out, and having found him he said, “Do you believe in the Son of Man?” He answered, “And who is he, sir, that I may believe in him?” Jesus said to him, “You have seen him, and it is he who is speaking to you.” (John 9:35-37 ESV)Jesus refers to Himself in the third-person rather frequently as the Son of Man, but this is a unique example; "It is He who is speaking to you." The Spirit is revealing His identity to the once-blind man through the flesh of Christ. Working through the flesh of Jesus, the Spirit opened this man's physical eyes to see the physical incarnation of Jesus, and again through Jesus' flesh, the Spirit opens this man's spiritual eyes to see that in doing so he has beheld the Messiah.
The Son of Man is the embodiment of Christ as He walks and talks, the mortal shell that would be killed and resurrected.
Now the Spiritual being of Christ is a little more difficult to pin-down, because He is rather encompassing.
So they said to him, “Who are you?” Jesus said to them, “Just what I have been telling you from the beginning. (John 8:25 ESV)A word used in most translations in that verse is, "beginning," instead of, "start." For the most part, same definition. There is a reference in chapter nine (specifically, verse thirty-two), where it's said that never since the world began had someone been given sight that had been born blind. In essence, not from the beginning had someone who was born blind been healed. The Spirit is revealing through the flesh of Jesus again exactly who He is; He has been telling them from the beginning who He is.
Another example is John 8:56-58.
Your father Abraham rejoiced that he would see my day. He saw it and was glad.” So the Jews said to him, “You are not yet fifty years old, and have you seen Abraham?” Jesus said to them, “Truly, truly, I say to you, before Abraham was, I am.”That seems to have rather upset them, seeing as they then tried to kill Him . . . Again.
My point in saying this is that He has been telling them (us) of Himself through the prophets since time immemorial. Before He used prophets to speak through, witness was made of Christ, even so far back as Genesis chapter three, when He declares that the woman's offspring would bruise (or, as Paul says, crush) the head of Satan.
From the beginning, He has been telling us who He is. Through His Word, through His prophets, through His Law, through creation. We are, therefore, without excuse.
