The Word of God is a powerful weapon inflicting His grace, mercy and peace.

Hebrews 4:12–13 (NIV)
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. 13 Nothing in all creation is hidden from God’s sight. Everything is uncovered and laid bare before the eyes of him to whom we must give account.

Article 11: The Holy Spirit’s Work in Conversion
Moreover, when God works true conversion in the elect, God not only sees to it
that the gospel is proclaimed to them outwardly,
and enlightens their minds powerfully by the Holy Spirit
so that they may rightly understand and discern the things of the Spirit of God,
but, by the effective operation of the same regenerating Spirit,
God also penetrates into the inmost being,
opens the closed heart,
softens the hard heart,
and circumcises the heart that is uncircumcised.
God infuses new qualities into the will,
making the dead will alive,
the evil one good, the unwilling one willing, and the stubborn one compliant.
God activates and strengthens the will so that,
like a good tree,
it may be enabled to produce the fruits of good deeds.
Summary
Libraries are filled with all sorts of good literature - books that tell exciting stories; books that a significant impact on history; books written decades or even centuries ago that continue to influence people today. But for as good as so many books are, none of them could come close to be described in the way that the Word of God is in today's passage.
Other books can make an impact in lives and societies, but only the Bible can be described as alive and active. The author emphasizes the word alive in the original text by beginning the sentence with it. Literally translated it reads: Living is the Word of God and energēs - that is, it's energetic, effective and at work.
God's Word is a dangerous weapon, sharper than any double-edged sword. But whereas a weapon inflicts bodily damage, scripture causes injury in a way that ultimate results in spiritual healing, piercing even to the point of dividing soul and spirit (NET) as it judges the thoughts and attitudes of the heart. What else in this world - weapon or otherwise - could do something even remotely close to that?
Nothing can hide from this weapon's power. God sees all, and through His Word He speaks to all things. Everything is uncovered and laid bare, our passage continues, capturing both the breadth and scope of God's Word as well as the way it humbles those who hear it: everything is naked and exposed to the eyes of Him to whom we must render an account.
Dig Deeper
Weapons inflict their damage indiscriminately. That is, a fired bullet will strike whatever it's aimed at, a sword will cut into any flesh it strikes, and a bomb will level everything in its blast radius.
God's Word is different in that regard. Many people don't even flinch as its proclaimed and preached to them; the words just sort of bounce off as if they were wearing some sort of spiritual body armor. That's the ironic thing about scripture: God's weapon only penetrates those whom He loves and has chosen (although, scripture leaves its mark on all who hear it).
The Canons here help explain how it is that God guides and directs this weapon's power in a two stage process. First, He uses its proclamation to enlighten their minds powerfully by the Holy Spirit so that they may rightly understand and discern the things of the Spirit of God. But then the next stage kicks in: by the effective operation of the same regenerating Spirit, God also penetrates into the inmost being, opens the closed heart, and softens the hard heart.
Our job is to simply take up and bear this weapon God has provided. Just as one who fires a gun is called a 'shooter,' one who bears this double edged sword is called a 'preacher.' And we're all called to be preachers. Most of you haven't been tasked with proclaiming it from behind a pulpit, but you can and must learn to wield this weapon well in all you do and say.
ACKNOWLEDGE WHO GOD IS: Our Father, whose Word has tremendous power;
ALIGN YOUR LIFE WITH GOD'S WILL: Thank God for using this 'weapon' to penetrate your soul & spirit, and pray that you'll use it effectively;
