Matthew Henry's Concise Commentary
The Holy Scriptures are the word of God.
and granted, not meant to divide believers--so, if you will just accept all of my interpretations, we'll all be fine!
but seriously, other commentaries have some interesting reflections on the..."proper" definition of "Word of God" here--that it is Christ, that it is Judicial Power, etc...the Word is alive, and i think limiting it to our own understanding--while that may surely also be valid--is a big mistake. I have witnessed 3 or 4 different reflections from one verse, personally.
