4 And my language and my message were not set forth in persuasive (enticing and plausible) words of wisdom, but they were in demonstration of the [Holy] Spirit and power [a proof by the Spirit and power of God, operating on me and stirring in the minds of my hearers the most holy emotions and thus persuading them],
5 So that your faith might not rest in the wisdom of men (human philosophy), but in the power of God.
6 Yet when we are among the full-grown (spiritually mature Christians who are ripe in understanding), we do impart a [higher] wisdom (the knowledge of the divine plan previously hidden); but it is indeed not a wisdom of this present age or of this world nor of the leaders and rulers of this age, who are being brought to nothing and are doomed to pass away.
7 But rather what we are setting forth is a wisdom of God once hidden [from the human understanding] and now revealed to us by God–[that wisdom] which God devised and decreed before the ages for our glorification [to lift us into the glory of His presence].
8 None of the rulers of this age or world perceived and recognized and understood this, for if they had, they would never have crucified the Lord of glory.
9 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.]
10 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].
