Final answer:
The Samaritans knew that Jesus was the Savior of the world, as per John 4:42.
Step-by-step explanation:
According to John 4:42, the Samaritans recognized that Jesus was indeed the Savior of the world after He spent time with them. Initially, they might have known Him only through the testimony of the woman at the well, but after hearing Him themselves, they came to this conclusion on their own. It is an important moment that highlights the universal nature of Jesus' message and mission, transcending cultural and religious boundaries of the time, and showing acceptance of the Samaritans despite the animosity between them and the Jews.
