After enumerating the essential defensive pieces of our spiritual armor in Ephesians 6:11-17, the Apostle Paul admonishes us to take up our one offensive spiritual weapon. Whereas all the other pieces of our armor are critical for our defense against the devil, only â€œthe sword of the Spirit, which is the Word of God,â€ can be used by us to fight off our spiritual foe.
If we are ignorant of Godâ€™s Word we are essentially unarmed against our spiritual adversary. Satan can freely attack us at will without any fear of being repelled by a sword of the Spirit wielding Christian soldier. Not knowing Godâ€™s Word leaves us with nothing to fight back with against the wicked oneâ€™s unrelenting war on us. Therefore, an unstudied Bible is the sign of an unarmed Christian soldier.
