Seems as though you'd profit from a study of prophets in the OT vs the NT and
WHY
Corinthians 14
was given as part of Scripture for our era.
YOUR SONS AND YOUR DAUGHTERS SHALL PROPHECY is a good place to start.
But, hey, given your love for throwing rocks--take up that crusade if that's what you feel God is instructing you to do. Obeying God is always more important than obeying man.
It might even hasten God working quicker, stronger, in a greater diversity of ways to help you understand the differences between Holy Spirit's operating in the OT vs the NT eras.
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?
Whose sons and whose daughters? Or do you just ignore the context.
