Mark 14:54
Peter followed Him afar off  .  .  .  and he sat with the servants, and warmed himself at the fire.
Peter learned a very valuable lesson here. You can’t fellowship with the world and remain faithful to the Lord. His association led him to deny that he even knew Jesus. Be very careful, young Christian, as to who are your “friends”. They can cause you to do things that your new nature would never even consider. Don’t sit and warm yourself by the fires of the world, no matter how cold it is outside.
