Hebrew 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 (NIV).

WOW how powerful is the word of God!

The word of God(the truth that is within the word of God or The Bible which is the inspiration of god according to 2 Tim 3:16, this can also be applicable to anything spoken by God ) is living (has life to it), and active (not only is it alive but it has power, and the writer goes on to illustrate it's power) Sharper than any double-edged sword(more powerful than THE MOST powerful of man made swords or weapons) it penetrates ( It has the power to change) to dividing( to take away the influence ) soul ( The word soul in Hebrew is Nephesh (נפש) which literally translates to "living being" or "living creature". According to Genesis 2:7 The LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul (KJV), also read 1 Cor 15:45, and Mat 16:25-26. Contrary to popular beliefs concerning the soul, the meaning of soul is "living being" or to put it into easier terms; the soul or life derives from the breath or spirit aligning up with the body. Notice the fact that I put the word "life" as another way to call the soul, this because that's what the soul is it's the life essence of the person. I would like for you to read carefully my statements concerning the soul. Maybe one day I will explain a little bit more concerning this very misunderstood subject but for now read the bible for yourself concerning this very misunderstood subject. So the Soul has to do with a persons LIFE). And spirit, ( this has nothing to do with the HOLY SPIRIT, it has to do with the carnal spirit that is within every person that is without God in their lives). In other word the word of God has the power to take away of the influence of the carnal nature (spirit of man) from the life (soul) of a person. Hallelujah for the word of God All-mighty, Hallelujah. Joint and Marrow (The writer is just continuing to show the power of the word of God. Notice the fact that you need both the bones and marrow to walk, so in a spiritual sense the word of god has the power to change the life that you live. This new way of living will be according to God's Instructions). It judges the thoughts and attitudes of the heart (God’s word allows him to know where you stand spiritually, or how close and far you are from him. This why every Christian is to examine themselves with the word of God for it is what you shall ultimately be judge according to).

May God Bless You
