1 Corinthians 2:4-7

And my message and my preaching were not in persuasive words of wisdom [using clever rhetoric], but [they were delivered] in demonstration of the [Holy] Spirit [operating through me] and of [His] power [stirring the minds of the listeners and persuading them], so that your faith would not rest on the wisdom and rhetoric of men, but on the power of God. 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; 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].
