I like Mr. Bond's answer. This answer is not to detract from that one but to add weight to it.
Here is my list of the times that Jesus came closest to explicitly claiming to be either Messiah, The Son of God, and the "I Am" of the OT (see LXX Deut 32:39, Isa 41:4, 43:10, 13, 25, 45:19, 46:4, 48:12, 51:12, 52:6).
- Woman at the well
John 4:25, 26 - The woman said, “I know that Messiah” (called Christ) “is coming. When He comes, He will explain everything to us.” Jesus answered, “The one speaking to you, I Am.”
This "I Am" declaration serves a dual function:
- to positively identify Himself as Messiah
- to affirm that Jesus is the "I Am" of the OT (see above OT references).
- John 5 - Healing at the Pool of Bethesda
The healing of the man at the pool of Bethesda followed by an extended discussion between the Jews and Jesus in John 5 is a special event where Jesus makes repeated claims about His divinity and equality with the Father; thus, it deserves special attention.
[Jesus performed seven miracles on the Sabbath: Mark 1:21-28, 29-31, 3:1-6, John 9:1-16, Luke 13:10-17, 14:1-6, John 5:1-18. In several of these, Jesus was accused of breaking the Sabbath and had to defend His actions. The differences in His defense are significant. In Mark 3:1-6, John 9:1-16, Luke 13:10-17, Jesus defends His actions on the Sabbath by essentially claiming He was doing good, etc.]
However, in John 5:1-18, Jesus heals the man at Bethesda on Sabbath. In this case, Jesus made no attempt to defend Himself by claiming that He was doing good etc. Rather He claimed that this was part of His regular job of working continuously just as the Father does (compare Col 1:17) and thus was not guilty of Sabbath breaking.
This is significant; Jesus’ defense in John 5 was essentially His divinity as He states several times in the subsequent discussion in John 5 – see below. Thus, Jesus' defense is unique here - He claims equality with the Father and the need to uphold the universe (Col 1:17), and thus, was not guilty of breaking the Sabbath.
The great problem that the Jews had in John 5, against which Jesus defends Himself, appears to have at least two facets:
- God (as they understood Him) is Almighty, Grand, Majestic and distant (despite the above). It was precisely this idea that the Gospel of John was written to dispel because in its opening prologue, we read: (John 1:18) - No one has ever seen God, but the one and only God, the One being in the bosom of the Father, has made Him known. Compare v1 where the Word is God.
- Jesus calls God the Father, "my Father" (V17), ie, His personal Father making Jesus equal with God. [I pause to note, and am supersized to observe that the Jews did not object to this on the basis of strict monotheism!! See appendix below.] This was acknowledged and unchallenged.
Jesus then goes on to say specifically in what aspects He was equal with the Father:
- V17 - Both the Father and Jesus must “work” continuously
- V17, 18 - Jesus claims the Father as his own personal Father
- V19 - The Father and Jesus work together in complete unity (not unison)
- V21, 26 - The Father and Jesus both have life in Themselves and can raise people from the dead at will
- V22 - The Father has committed all judgement to the Son
- V23 - All must honor the Son as they honor the Father
- V24, 25 - Jesus' “word” is the key to eternal life
Jesus then summons legal evidence that His testimony about Himself (as outline above) is valid under Jewish law because:
- V31-38 - He has a second, very weighty, witness in His Father.
- V39, 40 - Jesus claims to be the fulfillment of the Scriptures as Messiah
- V41-47 - Jesus comes in the Name of the Father and they do not believe Jesus; this, despite the fact that they believe people who come in their own name.
- John 8, Multiple Claims
John 8 is also significant because there are multiple claims made by Jesus:
- V12 - "I am the Light of the world" (Compare John 1:9, 9:5) - a direct allusion to Ps 27:1, "The LORD is my light and my salvation", and, Micah 7:8 "the LORD will be my light."
- V23, 24 - Then He told them, “You are from below; I am from above. You are of this world; I am not of this world. That is why I told you that you would die in your sins. For unless you believe that I am, you will die in your sins.”
- V28 - So Jesus said, “When you have lifted up the Son of Man, then you will know that I am, and that I do nothing on My own, but speak exactly what the Father has taught Me.
- V58, 59 - “Truly, truly, I tell you,” Jesus declared, “before Abraham was born, I am!” At this, they picked up stones to throw at Him. ...
- John 10:30, 31, 33
I and the Father are one.” At this, the Jews again picked up stones to
stone Him. ... “We are not stoning You for any good work,” said the
Jews, “but for blasphemy, because You, who are a man, declare Yourself
to be God.”
- Peter's Confession
- Matt 16:16, 17 - Simon Peter answered, “You are the Christ, the Son of the living God.” Jesus replied, “Blessed are you, Simon son of Jonah! For this was not revealed to you by flesh and blood, but by My Father in heaven."
Note the dual title of (1) Christ/Messiah, and, (2) The Son of God
- Trial before the Sanhedrin
- Mark 14:61-64 - Again the high priest questioned Him, “Are You the Christ, the Son of the Blessed One?” “I am” said Jesus, “and you will see the Son of Man sitting at the right hand of Power and coming with the clouds of heaven.” At this, the high priest tore his clothes and declared, “Why do we need any more witnesses? You have heard the blasphemy. What is your verdict?” And they all condemned Him as deserving of death.
Note that in this instance, Jesus effectively claims several things, namely:
- That He was the Christ/Messiah
- The Son of God
- The "I Am"
- The Son of Man
Note that claiming to be a human messiah was nothing new. However, explicitly claiming to be both human (the Son of Man) and divine (the Son of God) and Messiah all at once, was (to them) quote blasphemous; but only if it was not true!
- Arrest in the Garden
John 18 records the arrest of Jesus in the Garden and the exchange between Him and the mob:
4 Jesus, knowing all that was coming upon Him, stepped forward and asked them, “Whom are you seeking?”
5 “Jesus of Nazareth,” they answered.
Jesus said, “I am.”
And Judas His betrayer was standing there with them. 6 When Jesus
said, “I am,” they drew back and fell to the ground.
7 So He asked them again, “Whom are you seeking?”
“Jesus of Nazareth,” they answered.
8 “I told you that I am.” Jesus replied.
In this instance, the "I Am" of Jesus clearly serves a dual function:
- to positively identify Himself as the Jesus of Nazareth whom they are seeking to arrest
- to affirm that Jesus is the "I Am" of the OT, as confirmed by the fact that this declaration of His divinity made the arresting mob fall backwards.
- Thomas' Confession
- John 20:28 - Thomas said to him, ‘My Lord and my God.’ [literally, The Lord of me and the God (ho theos) of me]. Jesus them commended Thomas for finally arriving at this conclusion (contrast Acts 10:25, 26, Rev 19:10, 22:8, 9)
