The weapon of choice. Whilst all other elements are primarily to protect us, the sword allows us to also disarm and make an advance on what tries to control us.
This most powerful of weapons is the word of God.
The same word of God that brought all of creation into being. – Hebrews 11:3
The same word of God that saves lives from captivity. – John 8:31-32
The same word of God that is alive and relevant today…
For the word of God is alive and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart. – Hebrews 4:12
