1 Corinthians 2:9-12

9But, as it is written,

kWhat no eye has seen, nor ear heard,
nor the heart of man imagined,
what God has lprepared mfor those who love him”—
10these things nGod has revealed to us through the Spirit. For the Spirit searches everything, even othe depths of God. 11For who knows a person’s thoughts pexcept the spirit of that person, which is in him? So also no one comprehends the thoughts of God except the Spirit of God. 12Now qwe have received not rthe spirit of the world, but the Spirit who is from God, that we might understand the things freely given us by God.
