约翰福音第三章第1—8节耶稣说人若不重生，就不能见神的国。重生就是受了圣灵的洗从圣灵而生。被圣灵重生的时候，就像风吹一样，不知道圣灵如何做的工。人若不重生就不能见神的国，从灵生的就是灵。可见，基督徒被圣灵重生之后，就是灵。

约3:1 有一个法利赛人、名叫尼哥底母、是犹太人的官。
Now there was a man of the Pharisees named Nicodemus, a ruler of the Jews.
约3:2 这人夜里来见耶稣、说、拉比、我们知道你是由 神那里来作师傅的．因为你所行的神迹、若没有 神同在、无人能行。
The same came to him by night, and said to him, "Rabbi, we know that you are a teacher come from God, for no one can do these signs that you do, unless God is with him."
约3:3 耶稣回答说、我实实在在的告诉你、人若不重生、就不能见 神的国。
Jesus answered him, "Most certainly, I tell you, unless one is born anew, he can't see the Kingdom of God."
约3:4 尼哥底母说、人已经老了、如何能重生呢．岂能再进母腹生出来么。
Nicodemus said to him, "How can a man be born when he is old? Can he enter a second time into his mother's womb, and be born?"
约3:5 耶稣说、我实实在在的告诉你、人若不是从水和圣灵生的、就不能进 神的国。
Jesus answered, "Most certainly I tell you, unless one is born of water and spirit, he can't enter into the Kingdom of God!
约3:6 从肉身生的、就是肉身．从灵生的、就是灵。
That which is born of the flesh is flesh. That which is born of the Spirit is spirit.
约3:7 我说、你们必须重生、你不要以为希奇。
Don't marvel that I said to you, 'You must be born anew.'
约3:8 风随着意思吹、你听见风的响声、却不晓得从那里来、往那里去．凡从圣灵生的、也是如此。
The wind blows where it wants to, and you hear its sound, but don't know where it comes from and where it is going. So is everyone who is born of the Spirit."
