1 Corinthians 2:9-13

but just as it is written [in Scripture], “THINGS WHICH THE EYE HAS NOT SEEN AND THE EAR HAS NOT HEARD, AND WHICH HAVE NOT ENTERED THE HEART OF MAN, ALL THAT GOD HAS PREPARED FOR THOSE WHO LOVE HIM [who hold Him in affectionate reverence, who obey Him, and who gratefully recognize the benefits that He has bestowed].” [Is 64:4; 65:17] For God has unveiled them and revealed them to us through the [Holy] Spirit; for the Spirit searches all things [diligently], even [sounding and measuring] the [profound] depths of God [the divine counsels and things far beyond human understanding]. For what person knows the thoughts and motives of a man except the man’s spirit within him? So also no one knows the thoughts of God except the Spirit of God. Now we have received, not the spirit of the world, but the [Holy] Spirit who is from God, so that we may know and understand the [wonderful] things freely given to us by God. We also speak of these things, not in words taught or supplied by human wisdom, but in those taught by the Spirit, combining and interpreting spiritual thoughts with spiritual words [for those being guided by the Holy Spirit].
