Where would I find such a study? I would appreciate an authoritative source, ie scripture. Obviously that's not in the OT anymore, as you've just declared the OT to be obsolete to the NT era Christian. Where is this "more up-to-date" guide to testing the prophets? I don't find one in 1 Corinthians 14.
I must also ask whether you are testifying that, in this NT era, God has changed the rules re prophetic utterances? Are you claiming that what was once sinful (and thus damning) behavior, God now declares holy and acceptable? Or are you bearing witness that God has developed a speech impediment when speaking to His prophets, so that they cannot understand Him clearly? Or has the world become so utterly sinful, that God no longer can figure out what the future's gonna be?
Have declared no such thing.
And you know it.
You are the ones insisting on an Old Testament response to a New Testament reality.
Have you decided the NT is of little or no value to the Christian life?
