Soldiers, mercenaries, terrorists.  

Any of the above will do.

...

With a boldness unparalleled, these agents of warfare penetrate deep behind enemy lines.  Their mission is clear; leave a wake of destruction through stealth, planting of minefields, and ambush of unsuspecting and unprepared combatants.

Even though multitudes of their fellow soldiers have been discovered, trapped and eliminated, they keep coming, undeterred as madmen from the denizens of Hell.  Because that is exactly who they are.

The demonic minions of Satan never rest, never tire, never waver from the destruction of their enemy; which is that fellow or lady in the mirror, by the way.

Only one thing stops them in their tracks.  One weapon that brings them to their knees.

"the sword of the Spirit, which is the word of God."  [Eph 6:17]

And of course Jesus, who is the Living Word.

And He healed many who were ill with various diseases, and cast out many demons; and He was not permitting the demons to speak, because they knew who He was. [Mark 1:34]

I implore you as I remind me:

1.  Put on your armor and keep it on  [Eph 6]

2.  Guard your heart [Prov 4:23]

3.  Pray and Read the Word, especially when the forces of evil strike, intent on sabotaging your heart and faith.

In the strong name of Jesus, Amen.
