The Word of God Is a Sword
Ephesians 6:17 (ESV) and take the helmet of salvation, and the sword of the Spirit, which is the word of God,
Hebrews 4:12 (ESV) 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.
The Word of God Is a Hammer
Jeremiah 23:29 (ESV) Is not my word like fire, declares the LORD, and like a hammer that breaks the rock in pieces?
