Hebrews 4:11-12

Amplified Bible, Classic Edition

¹¹ Let us therefore be zealous and exert ourselves and strive diligently to enter that rest [of God, to know and experience it for ourselves], that no one may fall or perish by the same kind of unbelief and disobedience [into which those in the wilderness fell].

¹² 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 ^[a]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.
