Our Scripture reading today is Luke 22:55-57.
 
Verse 55, "And when they had kindled a fire in the midst of the hall, and were set down together, Peter sat down among them."
 
The Lord Jesus is now in "custody" and is being led into the high priest's house.  Our Scripture text today centres around a fire where Peter has joined a group people who more than likely were not followers of Jesus Christ.  Peter entered into a place by himself and set himself up for the temptation that he would ultimately face.
 
We are to be salt and light in this world of darkness.  This command can be followed while at the same time we are coming out from among those who are in darkness.  It is not wise to roll around in the muck and mire of the world in order to have an opportunity to at some point share the Gospel.  It usually does not work out that way.  Let's be careful how close we are sitting to the world!  Don't set yourself up for temptation.
