Acts 17:21

Now all the Athenians and the foreigners who lived there would spend their time in nothing except telling or hearing something new.

What are you doing with your time?  Do you spend it on social networks, watching TV or are you spending it with God? The Athenians who worshipped idle Gods and engaged in religion as a hobby thought to question and mock Paul as a pass time. But Paul who spent his time with God revealed their ignorance through the word of God. Guard your time and use it wisely for you never know when your Paul will visit you.
