John 4: 25-26.
The woman saith unto Him, I know that Messias cometh, which is called Christ: when He is come, He will tell us all things.
Jesus saith unto her, I that speak unto thee am He.
It seems that the woman tried to side-step Jesus’ words when she said, “Well, when Messiah comes He will explain everything.”
Jesus responded to her in plain words: “I AM!”
The King James translators often added words here and there for clarification. Those words are in italics. In verse 26, the italicized word is He. Which, if you omit it, takes us back to God’s statement in Exodus 3:14, the first time we see the words God used to identify Himself.
Moses, at the burning bush, was commissioned by God to go to the Israelites and declare that he has been sent to rescue them from Egypt. When he asks, “Whom shall I say has sent me?” God replies, “Tell them that I AM has sent you!”
God is the great I AM. He simply IS. No beginning, no end, He is the eternal Spirit come to earth in human form, and He is now speaking face to face with the Samaritan woman. This is an amazing moment in the history of God with mankind. He declares Himself in plain words that no one else can use, because He is the only I AM. Anyone else who tries to identify that way is a fraud.
