Just a comment . . . when Matthew tells us this, we KNOW he was inspired by the Holy Spirit. Does this give us license to hunt through the Bible for passages we can appropriate for our own use and call it "the Spirit"?
I realize that is a pointed characterization, but how can such a practice be demonstrably different?
Without something authorative, we have thousands and millions of voices all claiming supernatural revelation, and all saying different things. We do have something authorative, if we will accept it as such. Our Bible.
Such thinking as portrayed above can lead to some really bizarre ideas, limitless as the imagination of men. If we stick to what is actually written, then we will find God's ideas without interjecting our own.
You Have the Spirit of Truth in you, do you not? (Rhetorical ?) You have the Unction of the Holy Ghost? Do You trust in HIM to guide you into all Truth or do you trust your own intellect? My Intellect has let me down so many times I cannot count them so I have learned to lean on the Unction of the Holy Ghost and His ability to lead us into Truth.
