No weapon forged against you will prosper
Author
Charles Spurgeon
Summary: The enemy and their forges are making weapons to destroy the saints, but they will not prosper. The contest of languages is also a threat, with slander and falsehoods being like poisoned arrows. However, the Lord promises that even if we cannot silence tongues, we will escape being ruined by them. The mouths of those who speak against us will be silenced, and their falsehoods turned to our honor.
There is a great hammering in the forges and the enemy's forges. They are making weapons with which to annihilate the saints. They couldn't even do that if the Lord didn't allow them; for He has created the smith who blows the coals into the fire.
But see how diligently they labor! How many swords and spears they mold! It does not matter, because on the blade of each weapon you can read this inscription: it will not prosper.
But now listen to another noise: it is about the contest of languages. Tongues are more terrible instruments than those that can be forged with hammers and anvils, and the evil they inflict cuts deeper and has a greater reach. What will become of us now? Slander, falsehood, innuendo, ridicule: these are poisoned arrows; How can we face them? The Lord God promises us that if we cannot silence tongues, we will at least escape being ruined by them. They condemn us for the moment, but we will condemn them at last, and forever. The mouths of those who speak will be silenced, and their falsehoods will be turned to the honor of those good men who suffered because of them.
