All the devil's tricks!

(J. C. Philpot, "Contemplations & Reflections")

"So that we would not be outwitted by Satan; for
 we are not ignorant of his schemes." 2 Cor. 2:11

Satan is so wily . . .
  his agents so surround us,
  their designs are so masked,
  their language so plausible,
  their manners so insinuating,
  their appearance often so imposing,
  their arguments so subtle,
  their activity so unwearied,
  their insight into our weaknesses so keen,
  their enmity against Christ and His gospel so implacable,
  their lack of all principle and all honesty so thorough,
that the net may be drawing around us, before we
have the slightest suspicion of these infernal plots
being directed against us!

"Put on the whole armor of God, that you may be able
 to stand against all the devil's tricks!" Ephes. 6:11
