God's Word.

Hebrews 4:12-13

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. 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.

Sharing of the word:

My dear children, When the word of God is spoken it is able to penetrate deep within a persons innermost being. God's word is so powerful that it divides the joint and marrow, between the thought and intent and between the soul and the Spirit.
The word of God represents the hightest authority in the universe.
The gift enables us to see which spirit force is at work and the word reveals the depths of our own life. When the word of God is spoken into someones life it produces a effect in the person and causes one to repent.
It is only when we are in the word of God that we gain god's viewpoint on ourselves and others.
We must love the word, receive it, and allow it to change the way we think and act.
