Hebrews 4:12

New International Version

12 For the word of God is alive 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.

Isaiah 55:11

New International Version

11 so is my word that goes out from my mouth:
It will not return to me empty,
but will accomplish what I desire
and achieve the purpose for which I sent it.

New International Version

Psalm 1

Blessed is the one
who does not walk in step with the wicked
or stand in the way that sinners take
or sit in the company of mockers,
but whose delight is in the law of the Lord,
and who meditates on his law day and night.
That person is like a tree planted by streams of water,
which yields its fruit in season
and whose leaf does not wither—
whatever they do prospers.

Not so the wicked!
They are like chaff
that the wind blows away.
Therefore the wicked will not stand in the judgment,
nor sinners in the assembly of the righteous.

For the Lord watches over the way of the righteous,
but the way of the wicked leads to destruction.
