The Word of God

is,


Jesus Christ;
The Word;
The Bible.

In the beginning was the Word,
and the Word was with God,
and the Word was God.
John 1:1


And the Word was made flesh and dwelt among us, (and we beheld His glory, the glory as of the only begotten of the Father,) full of grace and truth.
John 1:14

It is the Spirit that quickeneth;
the flesh profiteth nothing:
the words that I speak unto
you, they are Spirit and
they are Life.
John 6:63
 
...For the Word of God is quick,
and powerful, and sharper than any two-edged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and  is a discerner of the thoughts and intents of the heart. 

Hebrews 4:12
