You are a lamp.
Do you have a wick?
Do you have oil?
Is your shade cloudy or clear?
Is there a spark?
Your wick is the WordOfGod in you.
Your oil is the SpiritOfGod in you.
Your spark is the FaithOfChrist in you.
Your shade is your Heart.
To TrimYourLamp you make sure that you give attention to all the above. In so doing, the Light of the World, Christ Jesus, will shine forth out of you.
