Luke 22:55

And when they had kindled a fire in the midst of the court, and had sat down together, Peter sat in the midst of them.

Psychologically, Peter placed himself at a disadvantage by "warming himself by the devil's fire." Accepting favors of enemies of the truth is just as dangerous now as it was when Peter sat in the firelight so long ago.

It is refreshing indeed to recall that, a few days later, there was another fire by the seaside, kindled by the Lord himself, and like this one blazing forth at a very early hour in the morning: and by that other fire Peter confessed three times that he loved the Lord! (John 21:9).
