Jesus told a Pharisee who should have had spiritual insight,
“Do not marvel that I said to you, ‘You must be born again.’ The wind blows where it wishes, and you hear the sound of it, but cannot tell where it comes from and where it goes. So is everyone who is born of the Spirit’” (John 3:7-8).
We benefit from the wind without knowing everything about it. Likewise, we can benefit from the Spirit, being born of the Spirit without knowing everything there is to know about the Spirit, as revealed in the Scriptures.
Do not let your marveling about how something works keep you from obeying the Lord.
