In John 4:3-42, Jesus meets a Samaritan woman at a well and offers her living water. Despite initial misunderstandings, she realizes he is the savior of the world. This encounter parallels Jesus' ministry to Nicodemus in Chapter 3, showing that both a respected Pharisee and a marginalized woman need Jesus as the Savior for eternal life. The woman's past and societal status do not hinder Jesus' offer of salvation, highlighting his love for all people regardless of race, gender, or background. This story emphasizes that no one is beyond the reach of Jesus' grace and love, making him the Savior of the world for all.
