Hebrews 4:12
"For the Word of God is living 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."
2 Timothy 3:16
"All scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness."
Proverbs 7:1-5
"My son, keep my words and store up my commands within you. Keep my commands and you will live; guard my teachings as the apple of your eye. Bind them on your fingers; write them on the tablet of your heart. Say to wisdom, "You are my sister," and call understanding your kinsman; they will keep you from the adulteress, from the wayward wife with her seductive words."
