As I read today's devo I really enjoyed the two pictures of the swiss army knife and the fencing. The swiss army knife example stuck out the most. It made me think about the scripture in Hebrews which also says the Word of God is sharper than any two-edged sword.
For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart.
Hebrews 4:12 ESV
Thinking within the swiss army knife context, the sword or Word has multiple uses. Not only is it a tool of defense and attack against an enemy, but it is also a tool we use to help ourselves. Sometimes some things need cut off of us. Sometimes there is soul surgery that needs to be done and as we look to the Word, the perfect law of liberty, we see things there that should not be. The Word, which is Christ, then cuts those things out of us. We don't wield the sword the same at this point because we are using it differently but it is the same sword.
