Final answer:
In John 4:26, Jesus reveals to the Samaritan woman that He is the awaited Messiah, stating 'I who speak to you am He.'
Step-by-step explanation:
According to John 4:26, Jesus says to the Samaritan woman, "I who speak to you am He", referring to Himself as the Messiah they discuss. Just before this statement, the Samaritan woman speaks of the coming of the Messiah or Christ, and in response, Jesus clearly identifies Himself as that figure. This declaration is significant because it is a direct affirmation of his identity, and it comes in a context of a broader conversation about worship, salvation, and the breaking down of social and ethnic barriers.
