This interesting passage speaks of a time when Israel had no blacksmiths to make weapons and was without any armament to defend themselves. The enemy had succeeded to disarm Israel by removing their weapons, and those who forged them! He's attempting the same tactic today.
A blacksmith is someone who works with raw material and fire, and who knows how to form and shape liquid metal into powerful weapons. Anyone who works skillfully and accurately with the word of God is a spiritual "blacksmith". The enemy, who is constantly attacking the word of God, the sword of the Spirit, also seeks to silence or remove the spiritual blacksmiths of this world. If he can get rid of them – the battle is over.
We need to pray for God’s blacksmiths because the enemy is after them. Together with the fire of the Holy Spirit they forge the raw material of His word into powerful weapons which shape and mold God's people into His image and equip them for spiritual warfare and fruitfulness. But we are all called to be strong in the word, and to take it up as our primary weapon. Every spiritual blacksmith, himself started out as raw material which was shaped and formed by the fire of God to fight in this battle with Satan.
Michael, so, as the battle rages, pray for the protection of God's "blacksmiths", even as you submit to His process of shaping you into one, yourself. (George, Baht Rivka, Elianna & Obadiah)
