"For the Word that God speaks is alive and full of power [making it active, operative, energizing, and effective]; it is sharper than any two-edged sword, penetrating to the dividing line of the breath of life [soul] and [the immortal] spirit, and of joints and marrow [of the deepest parts of our nature], exposing and sifting and analyzing and judging the very thoughts and purposes of the heart."

Hebrews 4:12 - Amplified
