John 2–4 packs in four scenes. At a wedding in Cana, Jesus turned water into wine, His first miracle. His mother, Mary, told the servants, “Whatsoever he saith unto you, do it” (John 2:5), which is great advice for eight-year-olds. Then at Passover, Jesus found people selling animals and changing money inside the temple. He drove them out and said, “Make not my Father’s house an house of merchandise” (John 2:16). The temple is sacred, and Jesus protected it.
In John 3, a Jewish leader named Nicodemus came to Jesus by night. Jesus told him that a person must be “born again,” born “of water and of the Spirit,” to enter God’s kingdom. Nicodemus was confused and asked how a grown man could be born again. For your class this is exciting: being born of water is baptism, and being born of the Spirit is receiving the Holy Ghost. Most of them have just done both! In the same conversation Jesus taught John 3:16: Heavenly Father loves the world so much that He gave His Son.
John 4 is the Story Drama. Jews and Samaritans usually didn’t get along or even speak to each other. Jesus, tired from walking, sat at Jacob’s well at about noon (“the sixth hour,” John 4:6) and kindly asked a Samaritan woman for a drink. He offered her “living water”: water from a well leaves you thirsty again, but what He gives becomes “a well of water springing up into everlasting life” (John 4:14). He showed He knew all about her life (keep that detail simple for kids: He knew things no stranger could know), and He told her plainly that He is the Messiah. She left her waterpot, ran to town, and many Samaritans came to believe He is “the Saviour of the world.”
Two big ideas for eight-year-olds: Jesus knows each of them completely and loves them anyway, and the good feelings the world offers (a new toy, winning, screen time) run out, but Jesus keeps filling us as we keep coming to Him through prayer, scriptures, the sacrament and the temple.
