In conversation and even in one study I did I talk about spiritual swordsmanship. You don't become a master swordsman just because you are given a sword. That is why so many Christians today live in defeat. To become a master swordsman you must get to know your sword. In the military, especially basic training, soldiers are made to sleep with their weapons, or at least some drill instructors find this effective. The idea of spending time with their "sword" seems to make them better soldiers. There is also training on the firing range. When talking about a literal sword the same thing holds true. You must spend time with your sword. You need your hand to feel the grip, the way it balances in your hand, the way it responds to your own movement. So they train. They will pair up with another and practice blocks, thrusts, parries, and the like. The more time they spend getting to know their sword and the way they can control it, the better swordsman they become.
In the spiritual sense, the Word of God, as I've already pointed out, is our sword. We have to spend time with God's Word. We have to get it into us, but intellectually and spiritually. Intellectually only helps us so far. We only understand the way it feels. As we begin to understand it spiritually we begin to see how we can use it in our own lives for our own battles. This is true because we are getting to know the "Sword Maker" better, and it is His Spirit, not ours, that will ultimately make us great and feared swordsmen of the Lord.
