The key theme of this chapter is “new birth and eternal life.” Nicodemus’s visit allowed Jesus to reveal the condition for entering God’s kingdom: being born of the Spirit. The core verse (John 3:16) highlights God’s love and salvation. John the Baptist closes by humbly confirming Christ’s supreme position.

耶稣是生命和丰盛的源头（把水变成酒）。

对神的敬拜不可被世俗利益玷污（洁净圣殿）。

耶稣的死与复活是信仰的根基（身体就是殿）。

真信仰不止是看见神迹，而是心灵深处对祂的认识与信靠。
