Someone once said that preachers and stand-up comedians were the only two vocations where you had to hold an audience merely by the content and delivery of your message.
As a result, many preachers try many different techniques in order to hold their listeners. Yet, Paul continued to trumpet the “foolishness of preaching” in 1 Corinthians 1:18-2:5. Take time to read over this passage right now:
For the word of the cross is folly to those who are perishing, but to us who are being saved it is the power of God.  For it is written,
“I will destroy the wisdom of the wise,
and the discernment of the discerning I will thwart.”
 Where is the one who is wise? Where is the scribe? Where is the debater of this age? Has not God made foolish the wisdom of the world?  For since, in the wisdom of God, the world did not know God through wisdom, it pleased God through the folly of what we preach to save those who believe.  For Jews demand signs and Greeks seek wisdom,  but we preach Christ crucified, a stumbling block to Jews and folly to Gentiles,  but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God.  For the foolishness of God is wiser than men, and the weakness of God is stronger than men.
 For consider your calling, brothers: not many of you were wise according to worldly standards, not many were powerful, not many were of noble birth.  But God chose what is foolish in the world to shame the wise; God chose what is weak in the world to shame the strong;  God chose what is low and despised in the world, even things that are not, to bring to nothing things that are,  so that no human being might boast in the presence of God.  He is the source of your life in Christ Jesus, whom God made our wisdom and our righteousness and sanctification and redemption.  Therefore, as it is written, “Let the one who boasts, boast in the Lord.”
[2:1] And I, when I came to you, brothers, did not come proclaiming to you the testimony of God with lofty speech or wisdom.  For I decided to know nothing among you except Jesus Christ and him crucified.  And I was with you in weakness and in fear and much trembling,  and my speech and my message were not in plausible words of wisdom, but in demonstration of the Spirit and of power,  that your faith might not rest in the wisdom of men but in the power of God.
I realize I could have placed that entire passage in bold typeface because it all communicates the same issue: God uses the “foolishness” of preaching to convey His wisdom, strength, power, and righteousness. Since this is His ordained method of conveying His truth, why do so many pastors and teachers look for other methods of men?
