Paul begins teaching the Athenians with what they know, and what they're good at. Then he offers them so much more: a God who loves them and holds them in caring hands. We also are loved and upheld by God, who is so much bigger than anything we can create with our own hands / imagination / efforts - our idols.
Sorry the video is bad. We lost internet in the middle of the sermon, but the audio is there. God's blessings to you.
