EPH 6:17

” And take the helmet of salvation, and the sword of the Spirit, which is the word of God;”

2 Timothy 3:16-17

” All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness,” 17 “that the man of God may be complete, thoroughly equipped for every good work.”

HEB 4:12

” For the word of God is living and powerful, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart.”
