From the Word 

The woman said to Him, “I know that Messiah is coming (He who is called Christ).  When He comes, He will tell us all things.”  Jesus said to her, “I AM I AM who is speaking to you.” 

    You may look at the above verse, look it up in your Bible, and conclude that something is wrong with my translation, since your Bible does not translate Jesus’ words in that way.  You will not find a translation into English like the one above because it isn’t good English. It is, however, what the text says.
    In the New Testament Jesus makes many “I AM” statements.  Most of them are in John.  The Hebrew name Yahweh (mostly translated “Lord”) means “I AM I AM.”  Jesus uses this name many times.  The Greek text uses two words, both meaning “I AM” to indicate what He says.  So we have the Greek saying “I AM I AM” showing that Jesus is calling Himself Yahweh, the Lord who interacted with the Old Testament people, and promised to come and save them.
    In John 4 Jesus is affirming that He is the promised Messiah, who is God the Lord.  He is God.  The woman is looking to know about the Messiah.  He tells her that He is the Messiah, and that the Messiah is God her Savior.
    Only God can be the deliverer of His people.  Only the sinless God can bear the sins of all people for all time.  So He did.  Yahweh, the one who used Moses to deliver His people from Egypt, has come to earth to deliver everyone from sin, death, and hell.  He is the redeemer of this sinful Samaritan woman.  He is my Savior, and yours.  He is my God, and yours. 
    During this year, we will look at I AM statements in the New Testament to learn about God the Savior who came to be our Savior.  These lessons will be from His own mouth, mostly from the Gospel of John.  We will learn about who Jesus is for us.
