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.
