Solomon wrote in his melancholy state of mind that there is nothing new under the sun. When Paul confronts the philosophers at Athens I am reminded of Solomon's words. We often face the same dilemma as Paul did in our day with the state of academia. Philosophers who love to debate their worldview but are not open to the truth of Jesus Christ.
The opponents of Paul in Athens were either fools, ignorant or vain in their thinking, which made them all fools. Foolishness is the failure to see and understand life as God has determined and created it. Fools lack the wisdom of God and His truth. They want to display their skills in proving their way is right without ever coming to know the truth.
"These times of ignorance are over," Paul declared. To know the truth and the one true God it begins with repentance that leads to faith.
