1 Corinthians 2:9-14

But, on the contrary, as the Scripture says, What eye has not seen and ear has not heard and has not entered into the heart of man, [all that] God has prepared (made and keeps ready) for those who love Him [who hold Him in affectionate reverence, promptly obeying Him and gratefully recognizing the benefits He has bestowed]. [Isa. 64:4; 65:17.] Yet to us God has unveiled and revealed them by and through His Spirit, for the [Holy] Spirit searches diligently, exploring and examining everything, even sounding the profound and bottomless things of God [the divine counsels and things hidden and beyond man's scrutiny]. For what person perceives (knows and understands) what passes through a man's thoughts except the man's own spirit within him? Just so no one discerns (comes to know and comprehend) the thoughts of God except the Spirit of God. Now we have not received the spirit [that belongs to] the world, but the [Holy] Spirit Who is from God, [given to us] that we might realize and comprehend and appreciate the gifts [of divine favor and blessing so freely and lavishly] bestowed on us by God. And we are setting these truths forth in words not taught by human wisdom but taught by the [Holy] Spirit, combining and interpreting spiritual truths with spiritual language [to those who possess the Holy Spirit]. But the natural, nonspiritual man does not accept or welcome or admit into his heart the gifts and teachings and revelations of the Spirit of God, for they are folly (meaningless nonsense) to him; and he is incapable of knowing them [of progressively recognizing, understanding, and becoming better acquainted with them] because they are spiritually discerned and estimated and appreciated.
