John 2–4 is full of beginnings. At a wedding in Cana, Jesus turns water into wine, the “beginning of miracles” (John 2:11). In Jerusalem He drives the money-changers out of the temple: “make not my Father’s house an house of merchandise” (2:16). Then two very different people come to Him. Nicodemus is a respected Pharisee and ruler who comes “by night” (3:2), maybe to avoid being seen. A Samaritan woman comes to a well at about the sixth hour, around noon (4:6–7). Jesus teaches both of them about a change so deep it’s like a new birth.
To Nicodemus He says, “Ye must be born again” (3:7) and explains that it means being “born of water and of the Spirit” (3:5): baptism and the gift of the Holy Ghost, followed by a lifetime of being changed by the Savior. Nicodemus doesn’t get it right away, but John shows him growing: later he defends Jesus in front of the other leaders (7:50–51) and helps bury Him (19:39). A night-time question can become a daylight disciple. John 3:16–17 is the Savior’s own summary of His mission: God gave His Son out of love, not to condemn the world but to save it.
Jews and Samaritans avoided each other, and a Jewish rabbi talking alone with a Samaritan woman was surprising even to His disciples (4:9, 27). Jesus asks her for a drink, offers “living water” and then shows He knows her whole story (4:16–18). He doesn’t shame her; He reveals Himself to her plainly: “I that speak unto thee am he” (4:26). She leaves her waterpot and runs to tell the town (4:28–29), and later the townspeople say they believe not just because of her words but because they heard Him themselves (4:42). For 14–16s, this is a chance to talk about reputation, being fully known, borrowed versus personal testimony, and the difference between things that satisfy for five minutes (likes, snacks, scrolling) and the Savior, who satisfies for good. Jeremiah 2:13 is a great cross-reference: people traded the fountain of living waters for “broken cisterns, that can hold no water.”
This week ends on fast Sunday. If you teach this lesson that day, keep the water in the object lesson for pouring only; nobody drinks.
