Does logos really mean word? Not really. Another Greek word means word.
But when you group words together to form a thought, then you have logos. My thoughts, and I am sure many will agree, might be irrational nonsense, and so would fall short of logos. On the other end of the spectrum, God's thoughts are certainly logos. In Genesis we see where God spoke the Universe into existence. So divine logos cannot be considered empty words, but the power of God embodied in expression, whether internally (thoughts) or externally (revelation.)
The NAS uses about 28 words to translate logos, many of them falling short of conveying the power embodied in the concept of logos. Because translators chose to use word (s) to convey the power of God embodied in expression, we must change our understanding of word to include both an organized expression by mere mortals, and God's Word, whether thoughts, external expression, or in the flesh.
When we consider logos and rhema we could follow the Septuagint and use the words interchangeable, but that obliterates whatever distinction might been intended. If we think of rhema as the box, the remarks or expressions, the surface shape of the statement or message, but we think of logos as the content of the box, the organized power of expression to bring about change, then I think we have at least a starting point.
