Advent 8: Pause for thought

Works of art often prompt thought and question, and thus become signs. Here what seems to be a sign (?), has become a work of art. I wonder what it may be saying to you? 

Good people think before they answer, but the wicked speak evil without ever thinking. 

Proverbs 15:28 

Reflect on what I am saying, for the Lord will give you insight into all this. 2 Timothy 2:7
