Acts 17
The Apostle Paul would use ANY opportunity available to preach the Gospel. When he got to Athens, he found a culture of philosophers who relished debating and discussing any thing new. They delighted in mental gymnastics. Paul himself had a great mind and was up for the challenge when given the opportunity to enter their arena of verbal stimulation.
Maybe he was calling upon his experience with the Athenians when he said, “We proclaim Christ! We warn everyone we meet, and we teach everyone we can, all that we know about him, so that, if possible, we may bring every man up to his full maturity in Christ. This is what I am working at all the time, with all the strength that God gives me.” [Col. 1:28,29 J.B. Phillips paraphrase]
