1 Corinthians 2:6-16 New King James Version (NKJV)
6 However, we speak wisdom among those who are mature, yet not the wisdom of this age, nor of the rulers of this age, who are coming to nothing. 7 But we speak the wisdom of God in a mystery, the hidden wisdom which God [a]ordained before the ages for our glory, 8 which none of the rulers of this age knew; for had they known, they would not have crucified the Lord of glory.
9 But as it is written:
“Eye has not seen, nor ear heard,
10 But God has revealed them to us through His Spirit. For the Spirit searches all things, yes, the deep things of God. 11 For what man knows the things of a man except the spirit of the man which is in him? Even so no one knows the things of God except the Spirit of God. 12 Now we have received, not the spirit of the world, but the Spirit who is from God, that we might know the things that have been freely given to us by God.
13 These things we also speak, not in words which man’s wisdom teaches but which the [b]Holy Spirit teaches, comparing spiritual things with spiritual. 14 But the natural man does not receive the things of the Spirit of God, for they are foolishness to him; nor can he know them, because they are spiritually discerned. 15 But he who is spiritual judges all things, yet he himself is rightly judged by no one. 16 For “who has known the mind of the Lord that he may instruct Him?” But we have the mind of Christ.
1 Corinthians 2:6-16 Amplified Bible (AMP)
6 Yet we do speak wisdom among those spiritually mature [believers who have teachable hearts and a greater understanding]; but [it is a higher] wisdom not [the wisdom] of this present age nor of the rulers and leaders of this age, who are passing away; 7 but we speak God’s wisdom in a mystery, the wisdom once hidden [from man, but now revealed to us by God, that wisdom] which God predestined before the ages to our glory [to lift us into the glory of His presence]. 8 None of the rulers of this age recognized and understood this wisdom; for if they had, they would not have crucified the Lord of glory; 9 but just as it is written [in Scripture],
“Things which the eye has not seen and the ear has not heard,
10 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]. 11 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. 12 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. 13 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].
14 But the natural [unbelieving] man does not accept the things [the teachings and revelations] of the Spirit of God, for they are foolishness [absurd and illogical] to him; and he is incapable of understanding them, because they are spiritually discerned and appreciated, [and he is unqualified to judge spiritual matters]. 15 But the spiritual man [the spiritually mature Christian] judges all things [questions, examines and applies what the Holy Spirit reveals], yet is himself judged by no one [the unbeliever cannot judge and understand the believer’s spiritual nature]. 16 For who has known the mind and purposes of the Lord, so as to instruct Him? But we have the mind of Christ [to be guided by His thoughts and purposes].
