Let's take a look at the context of 1 Corinthians 2:9-16:
"... as it is written:"No eye has seen,no ear has heard,no mind has conceived what God has prepared for those who love Him"- but God has revealed it to us by His Spirit.The Spirit searches all things, even the deep things of God. For who among men knows the thoughts of a man except the man's spirit within him? In the same way no one knows the thoughts of God except the Spirit of God. We have not received the spirit of the world but the Spirit who is from God, that we may understand what God has freely given us. This is what we speak, not in words taught us by human wisdom but in words taught by the Spirit, expressing Spiritual truths in Spiritual words. The man without the Spirit does not accept the things that come from the Spirit of God, for they are foolishness to him, and he cannot understand them, because they are spiritually discerned. The spiritual man makes judgments about all things, but he himself is not subject to any man's judgment: "For who has known the mind of the Lord that he may instruct Him?" But we have the mind of Christ."
Paul said: "Yet when I am among mature Christians I do speak with words of great wisdom, but not the kind that comes from here on earth, and not the kind that appeals to the great men of this world, who are doomed to fall." "Our words are wise because they are from God, telling of God's wise plan to bring us into the glories of heaven. This plan was hidden in former times, though it was made for our benefit before the world began. But the great men of the world have not understood it; if they had, they never would have crucified the Lord of Glory. That is what is meant by the Scriptures which say that no mere man has ever seen, heard, or even imagined what wonderful things God has ready for those who love the Lord. But we know about these things because God has sent his Spirit to tell us, and his Spirit searches out and shows us all of God's deepest secrets. No one can really know what anyone else is thinking or what he is really like except that person himself. And no one can know God's thoughts except God's own Spirit. And God has actually given us His Spirit (not the world's spirit) to tell us about the wonderful free gifts of grace and blessing that God has given us. In telling you about these gifts we have even used the very words given to us by the Holy Spirit, not words that we as men might choose. So we use the Holy Spirit's words to explain the Holy Spirit's facts. But the man who isn't a Christian can't understand and can't accept these thoughts from God, which the Holy Spirit teaches us. They sound foolish to him because only those who have the Holy Spirit within them can understand what the Holy Spirit means. Others just can't take it in. But the spiritual man has insight into everything, and that bothers and baffles the man of the world, who can't understand him at all. How could he? For certainly he has never been one to know the Lord's thoughts, or to discuss them with him, or to move the hands of God by prayer. But, strange as it seems, we Christians actually do have within us a portion of the very thoughts and mind of Christ." TLV
The TLV, in this case, follows the Nestle Greek Text very closely.
I would consider other references that you might have.
