Christ now reveals Himself to the woman: Jesus saith unto her, I that speak unto thee am He. Had He told the woman this to begin with, it would have appeared vanity. Now, having gradually awakened her to the thought of Christ, His disclosure of Himself is perfectly opportune. He is not equally open to the Jews, who ask Him, If Thou be the Christ, tell us plainly; (John 10:24) for this reason, that they did not ask in order to learn, but to do Him injury; whereas she spoke in the simplicity of her heart.
