Lent '09 - Day 8: What does this mean?

Do you see how these words from Jesus in Luke 8:16-18 connect?

• ¹⁶No one lights a lamp and hides it in a jar or puts it under a bed. Instead, he puts it on a stand, so that those who come in can see the light.
  
• ¹⁷For there is nothing hidden that will not be disclosed, and nothing concealed that will not be known or brought out into the open.
  
• ¹⁸Therefore consider carefully how you listen. Whoever has will be given more; whoever does not have, even what he thinks he has will be taken from him.

They make sense to me on their own, but they're clearly connected with words like "for" and "therefore". If you have any comments or thoughts, please share.
