How did Jesus begin to evangelize the woman at the well?
He met her where she was, right in the middle of Samaria. He didn't demand that she come to either His home in Galilee, or His "church" in Jerusalem.
He met her as she was: a sinful worshiper of a false god. He didn't require that she change before talking to her.
He took the conversation in a spiritual direction. She wasn't going to do so, so He took the initiative.
He made the "big promise" of eternal life early in the conversation. He did this even though it was clear that she was not tracking with His words.
