What is the Word of God?

First things first, when we talk about the Word of God, we may use the Hebrew word Dabhar, the Aramaic word Memra, or the Greek words Logos and Rhema.

Dabhar means “speech, word, speaking, thing, saying, utterance, business, occupation, acts, matter, or case (Hebrew Lexicon)." It is the act of talking and the word itself. Dabhar is active, creative, and alive. Dabhar is the Word and Wisdom of God.
Memra means "word or command (Hebrew Lexicon)." It is used in the Targumim to describe the Word of God as a Manifestation of God.
Logos means "a word, uttered by a living voice, embodies a conception or idea, what someone has said, decree, mandate or order, a dictum, a maxim, discourse, reason, the mental faculty of thinking, meditating, reasoning, calculating, account, cause, or ground (Greek Lexicon)." It is equated to Jesus Christ. It is a synonym of Memra.
Rhema means "that which is or has been uttered by the living voice, thing spoken, word (Greek Lexicon)." This the active, living Word of God, and is equated to Dabhar.

Now that we have covered the vocabulary, it is important to understand what the Word of God is not. So let's clear up some common misconceptions.

The Word of God is not...

A Book. Many books claim or are proclaimed to be the Word of God. None of them are. A book may contain how humans have heard, experienced, practiced, or understood the Word, but they are not Divine in and of themselves. Worship God, not idols of paper.
A Person. Jesus Christ is the only singular incarnation of the Word of God. We can be members of that body, but a person telling you they are the Word or Jesus is as foolish as an eye saying it the whole body.
Secret. We do not have to undergo elaborate rituals or even extensive education to access or practice the Word of God.
